Vesc brake The "X" in my drawing symbolizes a resistive load circuit. After the motor FOC settings, enter the Input Setup for ADC throttle calibration mode as below figure. Connect your VESC® to your computer using a mini/micro USB cable. AMECA has the entire VESC database. It is designed to integrate well with the VESC motor control firmware as well as with VESC Tool. Now i am having some issues with regenrative braking option as it stopping my bike so quickly that one day my motor mount get stucked in spok . Repository for the VESC Controller (ROS1 and ROS2) - rxdu/vesc_ros One area the VESC performs beyond expectation is the speed control. Electric vehicles may use the motor as a brake, generating energy So I am using a VESC for a project where I am re-doing an Kreweser electric trike-cooler-scooter-thing and have done most of the wiring but hit two spots that I could use some insight on:. Vehicle Equipment Safety Commission (VESC) was created by congress to assist states in creating rules, regulations or codes, embodying performance requirements or restrictions "for items of motor vehicle equipment. 12 fw 4. If a vehicle does not need mechanical brakes, but must be able to brake, it must use electronic brakes. p. I am using the Trampa VESC6. I continue doing tests and changes in the code, and the result is the same. I connected the M365 throttle control to ADC1 and I have good mapping 0-100, using current control setting. I have a go kart that is powered by a Vesc. :-) Another improvement: going downhill very slowly (walking pace) is much smoother now. DIY Hi there, I've just finished building my second DIY board and for the speed controller I've gone for a VESC based Maytech ESC. Since hackvana got so many orders for my ESC, Mitch wrote a wiki page about how to order VESC boards from him. Many state laws regulating automotive safety equipment were promulgated by the Commission of the Vehicle Equipment Safety. I have set my vesc regenerative brake current max to -5A, as i have a 5Ah battery (LiPo) and i know that charging a battery at more than 1c is not recommended for its life span. I am using FOC and when I press the full brake button I still read some non-zero e-rpm value. The publications listed is a compilation of regulated motor vehicle safety equipment which have been tested according to recognized standards by accredited AMECA testing laboratories. I have the motor current max brake at -60amps and battery current max If you run two VESC motor controllers on one battery, you need to cut your safe battery limits in half. 1025 Connecticut Avenue, NW Suite #1000 • Washington, D. Some cheap micro USB cables are designed for charging your Motor Current Max Brake: The maximum current output you allow your motor to produce when operated as a generator. Cons: Higher cost and steeper learning curve for beginners. Thanks to the speed mode of the VESC however the acceleration/braking is linear and very smooth. Last seen: 1 year 3 I assume this is according to timeout settings on the VESC, and so far it is desired behavour. When i am choosing "current reverse button" in vesc tool, i am able to reverse the motor by putting gnd to servo input. (but Does VESC reduce/disable regen braking based on battery voltage? So it's my understanding that, ideally, regen braking intensity should reduce or be entirely eliminated under several conditions, such as: batteries too cold temperature, batteries already full. That will be fixed once VESC Information; State MVA’s; Search; Contact; Certification; AMECA provides a registry of ISO-Certified and lists of DOT-compliant automotive safety parts. This is how I would set the CC control on my bike with a non-VESC controller: get up to the designed speed, push cruise and release the throttle. launched a laboratory testing program for police brake components using standard laboratory testing and the Original Equipment product as the baseline. 01(5. Contribute to UESTC-LIMITI/VESC development by creating an account on GitHub. 1) I have a two wire brake "switch" that is imbedded in the mechanical brake lever (It has mechanical rotor/caliper/pads). Every VESC must have: throttle (it's simple :)), freewheeling and some kind of brake. 00(6. 5A, 100A becomes 50A etc. In this tutorial we will configure multiple genuine VESC® motor controllers, using a CAN bus link cable. The video also shows -200A for the battery reverse current is most definitely too much/unsafe. From what ive read I need a switch of some kind to control turning the forward pedal into reverse. Let me know what you need to know for helping me heheh i have searched and tried all settings but no one is working for me. ; vesc_hw_interface wraps vesc_driver as a hardware interface to use Yes I have calibrated the throttle and brake using the input wizard on PC vesc-tool. inputs. By default it is 0 ****Introducing the amazing VESC® 6 MKVI Speed Controller, the sixth major product update of the world famous VESC 6 motor controller. I want to use the cadence output (which is 36 pulses/rev. i dont have any brake switches hooked up I'm using the VESC6 in my electric scooter. Full speed is around 50k Erpm. I connected to throttles one on ADC another one ADC 2. So, I want to have the regen brake on the vesc paired to the same brake lever on the m365 controller. 3) on an escooter. :) Additionally, I’d appreciate a detailed explanation of how to set up the brakes correctly on the VESC 75100. Then push the ADC controller throttle to max and Braking depends on two factors in terms of vesc settings, "Motor Current Max Brake" and "Battery Current Max Regen". 11000 bremskerl north america, inc. i am using a 3 pin throttle and using Im currently building a go-kart using a dual 75100. Currently, as soon as the speed is So, I want to have the regen brake on the vesc paired to the same brake lever on the m365 controller. The second VESC controller capable of hibernating, your board can conserve power while not in use - reducing power Throttle/ Brake/TFT screen wiring diagrams ADC Throttle parameters settings 1. The cruise control feature works for control type "Current Reverse ADC2 Brake Button" but does not work for "Duty Cycle Reverse Button", what might be wrong? The signal is definitely working -- brake light hooked up to the signal wire which also connects to the ADC2 lights up when the brake handle is pulled, and the voltage spikes to 2. VESC Tool Photos - Just another brake question , as I try to finish my Gokart project Is there anyone who know how to fix brake / keep motor position while stop ? One of the job of that hw is to make the speed input of vesc is zero, when braked, and all the mosfets on the hw will short the phase legs of the motor. If it does, how should I connect it to the controller properly? I’d love a step-by-step guide or a connection diagram if available. Have a look at the links under the Resources heading at the top of this page to find all files. I have tried to follow a "no braking when fully charged" rule which has helped and also stopping charging at 4. ISO I didnt realise the brakes wouldnt work during down ramping So i tested it out today and had to jump off the board as it shot off ramping down for my 10 second setting. dev Motor Wizard Guide: Step by Step, Troubleshooting etc. 12 hardware with ADC1 throttle and ADC2 brake on an eBike, the servo is intended to physically disengage the motor to reduce drag 2017 Benjamin Vedder benjamin@vedder. 2. Picture is as following: When the VESC is instructed to brake, the kinetic energy in the wheels is spin the magnetics around the copper wire. Plugged everything in and noticed the remote worked to spin the motors before running the vesc-project tool. My problem is that for this to work I need to brake the motor, but this means that the VESC will push current back into my psu. 12 (like a few others in here are too). Both are working. ; vesc_driver is the main library to drive VESCs. Our setup is two motors mechanically coupled directly. The VESC firmware is free software: you can redistribute it and/or modify it under the terms of the GNU No brakes in PID Speed Control mode Hi, I am controlling my two wheels robot using PID Speed Control mode which is the most suitable mode to my needs, but not everything works good. . • 20036; 250 Englar Plaza, Suite 1 • Westminster, MD • 21157 (202) 898-0145 (833) 898-0145 Push and release to enable and meet some condition to disable, such as touching the brake, pushing the cruise again. 3 don't think it happened as much on 5. Motor Current Max Brake = -160A Absolute Max Current = 270A. I want the winding machine do decelerate/brake as fast as possible (maybe not recommended with skateboards :) ). But my VESC is not braking hard. Paul I'd connect a multimeter on the ADC1/2 just to see if the VESC is getting a wrong input (like in my case) or if the Input is OK, but the VESC is not interpreting it the right way (as in my case with the fluctuating 5V) OR if some secondary function like Brake on ADC2 is stopping/interrupting the ADC1 signal (again:_like in my case as I was In VESC Tool, it would be great to have a Mapping page that allow to map inputs such as cruise control, reverse, accel, brake, UART, and so on. org email account allows us to respond to specific inquiries as well. But is quite loud when riding along on the skateboard. But when i am choosing "current reverse adc2 brake button" the same input does not reserve the motor. HI all, I have a throttle and brake issue. For example, when motor is idle (DUTY CYCLE =0) I would like to have much more current to start motor under load for few seconds , then I can make it lower. Currently it only runs on the test bench, the torque sensor signals are emulated by a blackpill board. bin' Then click the download button. Problem I have is at speed 0 and on steep hills. You need the capacitor to do the DCDC to increase the voltage above the back EMF of the motor. Choose the ADC control type you need. 12 with the latest firmware and switched from the old BLCD Tool to the new VESC Tool. 8 vesc where the brake stops working at full brake. Everything seems to be working well, except the reverse button. Very Bit of context I'm running 4. 0 ESC. 3FW) Version6. Thank you. link/YTShare SmartRing connected to slave VESC asks master VESC through CANbus for PPM value. So, this setup includes additional components. What I mean by this is that when the gas is pressed, the kart goes forward and when you press the brake Has anyone tried to implement an simple "breaking" light on VESC firmware? I'm working on a onewheel now, and was thinking about having ws2812b on te front and on the back, illuminating them accordingly, and changing intensity to have a "breaking" light. Thanks. I have a flipsky 75100 and I am trying to use regen with my 1500w direct drive motor. I would like it to be like how brushless rc cars are. 5A @ say Is is possible to use FOC without any braking current (like in other bldc controler) I mean when I set braking current to 0A, engine never stops ? I do'nt understand since there is some fiction behind the motor so it cannot continue to turn without eating current !!! Ctrl : VESC 7. pdf), Text File (. Still experimenting and I don't seem to understand a few things in the Vesc Tool. 0, but the app version is similar. (Like 1 command level skills - I know - poor) When the motor slows, firmware activates the (think it's openloop braking FOC) Could someone explain to me what is different between the functions mcpwm_set_current(float current); and mcpwm_set_brake_current(float current); We are trying to generate as much electrical power as possible using a VESC 4. Battery amps - for a p42a cell 30a continuous Big thanks to Marcin, Here is a really good video tutorial showing you how to change settings in the BLDC tool to configure the VESC for optimal input control using PPM, which is used by the common RC controller GT-2B. Log in or register to post comments; Mon, 2022-11-14 11:20 #4. I want to use a push button switch on the handlebars to swap the motor torque direction ie. 0)), but the actual braking never occurs if the erpm is more than the maximum I set in VESC-Tool, then the braking is not done. Packed with a variety of amazing new features, this VESC motor controller is certainly worthy of its pimpin’ gold logo. 4 rated at 80 amp continuous with 12 S battery, the motor max current detected is 100amp so it should fit quite well Need some advice to hook up an additional switch to my excisting Setup to activate regenerative Braking. The trouble is, as soon as you hit the brake, the wheels lock up. 15450 coni-seal corporation 16900 saeron automotive corporation Open the VESC Tool software and click 'Auto Connect' Once your FOCBOX has connected, you may get an alert letting you know that you need to update the firmware. Any value is accepted by this driver. 15v/cell, but occasionally I forget that the pack is full and get a VESC cut-out with a 50:50 chance of blowing the TVS Diode and DRV chip and in one case blowing a hole into the PCB beneath the TVS! I am confused about the full brake button on VESC Tool. The principle is that the kinetic energy on the motor and the load can be used as a generator through the DC motor to I'm assuming the VESC really does do regen charging (and not just a "short circuit brake"?) - how do it do that? Is there some kind of boost circuit? Is there magic with capacitors being charged from the battery, then put I'm using a 4. I noticed there is an option for Timeout Brake Current, set in amps. I am building a force feedback wheel using a hoverboard motor and a VESC. xx only. 12 FSESC controller in a tracked vehicle, and need to disable the brake. I need both forward and reverse directions, but also I want to have a possibility to immadiately stop a robot after releasing inputs from rc radio. The bike maintains the speed regardless of the incline or change in the load Different temperature cutoffs for acceleration and brake Done: 3. Basically it’s fine tuning the input data recieved from the TX. Besides VESC regenerative braking, another type of braking is the Dynamic Braking. " Just stumbled upon this thread as I am also having the same issue with my Maytech 50A SUPERFOC6. User login. 06. I believe this is due to the vesc basically shorting the phase leads together due to a lack of current flow. Different connection and settings on the vesc tool make different effects. Looking at the different modes i am wondering if there is a combi that works? Anyone an idea if that is feasible? Or is the combination bi-drectional joystcik and brake Events total: 30, the last ones are "set duty", "release_motor_override", "set current brake" (last one at 0 sec ago every time I check). 0 (mc_interface_set_brake_current_rel(1. 20. One forwards and one brake on adc 1 and 2 respectively. I tested the car with -40 amps max motor brake power and with -40 amps max battery regen (thats 160 amps on max by the 4 motors) . Doing anything else would melt or fry the VESC, or the Motor. I have benchwheel remote setup, dual VESCs with ppm input connected to master, slave via CAN. I set up the board using vesc-tool and had no problems. Link below:Twist Throttle (Golden/Gray) : https://bi Video is focused to my crazy cart kit but most info applies to any vesc adc application :) The kill switch can be wired in according to the VESC-Tool options. AMECA is always eager to assist the general public in quickly finding information and resources. Click App settings, General, App to use and choose ADC then app write in. The VESC motor control firmware. , ltd. The sound doesn't increase with extra current or braking. Result is an uneven acceleration. I have my brake levers set up correctly and have even tried setting the ADC input to make my throttle act as a brake after center voltage. The items in question comply with jurisdictional I'm using the 4. The jerking happens most when either slightly above or below the centre point as mentioned above. At slow rotor- generator speeds I should ask VESC to stop braking. i built a batt pack for it from sony vtc4s (16s8p). txt) or read book online for free. Created by InShot:https://inshotapp. And then the sensor wire to ADC1. It's a separate system (2 controllers, 2 motors, 2 batteries, 2 throttles). the brake power was still not enough for a 5 kg car and the 4 cell lipo overall voltage dropped from fully charged to AMECA and the VESC; History of the VESC; Brake Friction Testing; FAQ; Testing Laboratories; VESC Standards; FAQ. Motor Current Max Brake: 2. I drive the VESC with an ESP32 APP with CAN bus. i use foc mode and i'm very satisfied, but i found a problem : during downhill, if the bms interrupts recharging because the battery is fully charged,the result is that i lose brakes totally. It makes cutouts without reaching te currentlimit. Click 'OK'. 35v when i press the handle (real-time in the VESC tool app detects it), but the doesn't seem to shut off the motor at all. Supports smooth acceleration, torque control, and braking. The following will explain in detail. I'm using a pedal torque sensor to drive ADC1 in current+braking mode on a bike. Would I need to be able to communicate with the ESC via the VESC tool to activate its braking current capabilities or can I just plug a motor in and push against its spin? In this setup, I believe there is a way to have the VESC regen brake you down to the throttle's indicated setpoint. 20s Liion 21Ah. My problem is when i brake, then the motor brakes not smoothly. This is a very early attempt based on the VESC BMS and IO board firmwares, so there is a lot of functionality missing and several old settings still from the BMS. Click on 'UNITY' Click on 'VESC_default. Would like to connect an switch OR reedcontact to my Magura Hydraulic Brake so that if i touch the brake can use the thump throttle for motor brake. 1. Know the limits of your battery: Battery Current Max = 35A to 60A Battery Current Running 63100 motors with trampa vesc's and I'm getting like a brake hiccup ie the board brakes on its own whilst riding can I change anything in settings to prevent this ,on 5. 3 version with pwm app. My guess is the VESC is somehow losing track of the rotor when the brakes are applied and the motor is spinning too fast. Essentially the throttle will become a variable regen brake whilst the switch is pushed. Im also using adc and uart mode because im using the bluetooth display on my phone as my dash display. Extremely weak. 1: TODO 2018-03-16: Support for pedal sensor in ADC app (legal ADC1 is throttle with center brake and a button reverse. Upgraded from 3. You can wire it positive to 3V3 and negative wire to ground. I have an "Ewheel ADC adapter V2 for diy ebike escooter with vesc". This repository is composed as follows: vesc is a meta package to manage the other packages. current (and motor max brake current) to 60A (-60A) and battery max current (and max regen. 61 and brake to reverse works now. 02(6. I've hooked up a VESC 6 to a Xiaomi M365 hub motor and I'm getting good FOC control so far. This guide also inclu pev. This is done by controlling how much electricity the motor is This is for a generator application where I would start an engine with an amp input into the VESC, then turn this amperage off, then turn the brake on. I have a thumb throttle and linear hall sensor for braking wired up to my VESC. In this tutorial we will configure a single, genuine VESC® motor controller in combination with a PPM signal based radio controller in Current No Reverse with Brake mode. With NOOB level arduino skills, I coded a very simple command to write the brake current. 2 Just getting started with the VESC. Remotes throttles brake levers VESC Accessories Other Accessories Read This First Support. Top. VESC stands for Vedder Electronic Speed Controller and is an open-source ESC (Electric Speed Controller) that is used to control a multitude of devices like skateboard, Onewheel, or quadcopter. VESC tool is 2. I read many threads here, from what I understand, if you select ADC as the APP, the firmware will use the RX to GND to reverse. Can somone halp me? On the VESC 100/250, I would like to use a second thumb throttle for light variable regen braking, as well as separate hand e-brake switches on the mechanical brakes to cut motor for emergency braking (without regen). 47: 2018-03-06: Step/Dir app for CNC applications and similar. Username * Password * Create new account; Request new password; But then; i would like to be able to switch on the regen by a brake signal. Of course because hubs are weak motors without any kind of gear ratio. That all is valid for well designed IPM motors. AMECA has a clear line of ownership of VESC materials back to the creation of the VESC in 1958. Then click Setup Input to do ADC throttle calibration. It makes loud noise also. 3. Torbjorn. When we use hub motors - skate brakes are weak under 10 km/h, adding cloud wheels 105mm makes it more weak. For an electric skateboard a strong Timeout Brake is not appropriate, since the rider would not be prepared to a sudden hard braking force. se This file is part of the VESC firmware. I'm using a 4. 2 VESC and I have throttle on ADC1 Items: Flipsky 75100 75V 100A Single ESC Throttle Accelerator Bar Brake Handle Simple forward / reverse switch (for demonstration purposes) Adapter wire (for GND connection) GND wire*2pcs ADC mode Reverse and Cruise Mode wiring diagram: 1. Bun unfortunately for me this option does not seem to work for me. If you have made it this far, we would like to formally invite you to come I'm using the vesc 75_300 with firmwware 5. If Dynamic Braking module is able to communicate w/VESC, and VESC is aware module is present and active, Field Weakening routines could trigger the OvervoltImminent signal and VESC could forestall some undesirable protection behavior. M5 display: I have an M5 display, and I’m not sure if my controller (VESC 75100) supports it. How to I comply with the VESC? AMECA is the only organization with the original signed agreements regarding the VESC. Back to Welcome&Wizards and click AutoConnect. But for some reason no matter what I try or how many times I go through the setup wizards looking for settings to change VESC V-14 Minimum Requirements for Brake Component Wear Warning VESC V-15 Minimum Requirements for the Design of a Vehicle Identificatio VESC V-16 Minimum Requirements for the Design of a Vehicle Identificatio VESC V-17, Construction and Equipment of Mopeds. I would like to connect my brake lever (which has a switch built in) to the vesc for ebraking. Log in or register to post comments Automotive Manufacturers Equipment Compliance Agency (AMECA) has been registrar for VESC materials since AAMVA Discontinued it’s Equipment Compliance Program. I have the throttle input going into ADC1. This is not desirable for this application and other similar applications. However, note that the VESC may impose a more restrictive bounds on the range depending on its configuration. Your board tops out at ~28mph. So i am wondering if maybe I have to update either the remote controller's or the vesc's firmware or both or if this may be just a setting somewhere which is turned off. But you want two stages only, motor moving or not moving. Regards. The throttle and brake response is perfect BELOW 30-35mph, above which the brake will not respond properly. On VESC tool i typed a lot options like ( current no reverse Brake ADC2 or other ) and didnt get active anyway. 5A (because of the Max, current charge battery) The VESC acts as a DC/DC converter, so when the motor spins slowly (and generates a low voltage and possibly a high current), this gets transformed to the battery voltage at a lower current. The VESC tool seems perfect with the torque curves and other setting limits but I do not know how to use it I'm trying to use VESC to build a generator using the braking current functionality. Now I'm using a flipsky Dual FSESC4. On the left hand side of the VESC Tool, click on the 'Firmware' section. And I think Vesc Tool might be a good tool for this project. 12 VESC with regen battery current limit set to 20A and regen motor current set to 100A. Offline . (Button Underneath cursor). CAN messages from VESC use an extended ID (EID), containing the COMMAND and CONTROLLER_ID. The principle is that the kinetic energy on the motor and the load can be used as a generator through the DC motor to There are three stages currently: speed>minERPM; speed<minERPM; handbrake. Motor amps negative (braking) - Similar idea to above, but I typically go slightly lower on amps per side to make the brakes less grabby initially (personal preference). I am having aproblem with my fully FW updated VESC 75/300 R2. Definition at line 217 of file vesc_driver. What’s also cool, if you want a separate brake you can wire it to ADC2 and have Regen brake control. ESP32-S3 is peripheral/slave. 1FW) Version 3. I'm wondering though if there is a setting which applies regen braking when I let off the throttle, similar to original M365 regen, or similar to Front motor is a generic 350w m365 clone controller. My question is, what input do I connect the switch to? This works perfectly for most scenarios, however, at very low speed (coming to a stop) the braking resistance becomes extremely high. A external circuit that always pulls the ADC 1 throttle signal low when applying the brakes would be the best way to make sure that you can not pull the throttle while braking. (Use a lab supply and multimeter to double check the wiring before plugging into vesc) In the vesc tool you then need to select ADC throttle input. The VESC Environment is so much more than just a technical solution - its a rapid growing community of enthusiasts and experts, spread around the entire globe. In principle, ADC controllers are generally Even a slight trigger or brake produces the full sound. I have the max regen amps at -30 and the same with max battery regen amps. Just one on ADC2 seems doing nothing. Dynamic braking uses a different setup that the current is fed to a resistor. Today I updated my VESC 4. 12 300A MAYTECH I have the same problem with the (Maytech) VESC 4. Can't find any settings to disable the current-hold when its in neutral. This is the only way I could get reverse to work properly, so I wired the brake to switch the high side of the ADC1 pot to ground (thus interrupting the throttle signal and achieving braking). Home; About; VESC Information. Note: This guide shows the desktop VESC Tool 6. ADC or PPM, high or low. If you then change to 50% throttle, it will ebrake down to 50% speed. Here is a simplified diagram of what I am trying to do. My problem is the regen brake, that in R/C cars there are no BMS, without balancing it's not a good thing to charge like 5A into the battery In the 4in1 ESC I've used the "brake on stop", or "handbrake" function to stop the rotors, shortening the coils. to activate regen mode. cpp. if you are trying to make a motor I am new in this vesc forum, My hardware is the flipsky 75100. 1: TODO 2017-11-23: Proper torque-controlled brake from 0 speed. All of these resources can be found on the Public Information Resources sub-page under Programs: So, at first, I would like to benchmark regenerative braking to see if this is something to go further with. After all this the bike does not regen under Benjamin noted with the addition of LISP programming to VESC, that it makes easier to make a custom codes, such as custom PAS, but it is still a qute hard thing to do for a non-programmer. 2FW) Version 3. It lists the Is maximum braking power determined solely by the batterys maximum charge current (Therefore to increase braking power you have to add battery capacity). If you change it in the VESC tool by a few kHz, you can head a noticeable difference. Another example of why the VESC is superior. Hi, yesterday I was fiddling arround with different VESC SIX settings, and after my crash on caster board (with chinese esc) I wanted to set up timeout brake on my moutainboard. , currently on ADC2) to inhibit braking so that if there's forward pedal movement, even if torque/current goes to zero there will be no braking. Also, how is that different from switching the system off. brake: Commanded VESC braking current in Amps. What is the dfference between pressing the IB brake button and the larger full brake button? In FOC mode with braking=true, what does happen at PID speed=0? Braking always involves removing energy from the motor (and load). With more speed I should ask the VESC to apply more brake current. Next I have to install the controller in my tinker bike and do a real test ride Essentially, when motor is being driven at a high enough speed so that the duty cycle rises above 95% (to say 120%), the motor begins braking without any brake demand from me, VESC tool seems to think that the motor current and battery current are both 0, however with a torque transducer I have set up I can see that the motor is providing torque. Username * Password * Create new account; Request new password; hi im wondering if someone can answer some braking questions about an ebike project im working on. 10100 bosch brake components llc 10725 brake parts, inc. As If a vehicle does not need mechanical brakes, but must be able to brake, it must use electronic brakes. I use an Arduino, because I have a button that holds the PPM signal for cruise. The VESC tool still works for setting up the motor, but the app setting must not be done with the VESC tool at the moment, as it does not (yet) know the new functions. acceleration and braking/reverse. Is there anything in particular that i need to take note of when buying a 2x10uF capacitor? like the size or shape of the capacitor to be soldered to C18 and C26? The VESC is not capable of anything other than Regenerative braking. Would such a dynamic braking module damage VESC? Hi! my ESC (VESC 6 MK VI HP) is listed as having braking current capabilities and I was going to use it as a variable resistive torque on a test rig. Is there a mode or a way to get all 3 at the same time with ppm control. mc_interface_set_brake_current_rel is called with a value of 1. I am wondering if by varying the braking signal voltage with an arduino monitoring output voltage, I could keep the voltage output from the generator constant regardless of load. Excellent for high-current loads and precise motor control. However, the other noises remain almost identical. The "issue" I'm seeing is that if the throttle is on the brake turns the throttle into a reverse variable brake. I have speed ramps programed and with a normal ESC this controls the thrust/energy. To resolve the issue, navigate to "App Settings" -> "ADC" -> "Control Type" and Part1: VESC Tool Version 2. 11125 bridge brake products 12885 c&j material co. 0FW) Version6. How do I make the connection to the Vesc brake line? The -25A is the max brake power in the setup. i have brought a vesc and using it for my Ebike . FAQ on the VESC. If pedaling becomes too easy, braking kicks in. To power this I am currently using an ATX power supply but will probably upgrade to a 36v psu as the need for more torque comes. Hardware. current) to 60A (-60A). I now understand the regen brakes are the VESC's only way of slowing you down from higher speeds, which is fine, an advantage even! But the problem with my setup is I have two 6s It’s my understanding that the vesc can “recirculate” the regenerated power through the windings of the motor and the mosfets of the vesc to allow braking without generating any net power to the battery. In these scenarios, it would make sense to actively brake by applying negative If it is set to 60A, VESC can only eat 60A, so the braking time and braking distance will be extended. However, if you do the same with some SPM motors, you can expect fireworks and massive braking torques, stalling of the rotor etc. Since I am using a PSU to power the machine, it I am new to VESC and I am trying to better understand the regenerative braking algorithm when Control type = Current No Reverse With Brake. Currently I have no assembled PCBs or kits to sell, but you can order bare PCBs from hackvana with these gerber files. C. My first step was to set up a test bench with a driver motor connected to a generator motor (see pic). I know that it sets the duty cycle to 0. Brake line has 3 wires(5v, gnd, signal). After a few minutes of fiddling around it was pretty clear: the stuttering comes from braking all the time (accelerating-braking, accel, braking, a few times a second) AND the 5V pin on my first VESC has been badly soldered and connected with mOhms to a few kOhms resistance depending on "mood". 10730 brake parts international/ranger brake corp. Can your battery take that much charge current? You want to set the reverse battery current max to the max charge current your battery is able to accept and you would use the motor negative current setting to adjust the braking force: the more negative current you set, the more braking power VESC v4s are very prone to sudden failure at 12s voltages especially in regards to braking. If your friends board tops out at ~31mph and you were both going 30mph down the hill then that explains the difference. Only a very mild brake force can I have set Motor Max. (this will make it work according to legal when tested in a roller bank. AMECA List of VESC v 3 Brake Friction Material Edge Codes December 8 2017 - Free ebook download as PDF File (. It happening at the very first Break so no FET overheat! My Vesc Settings: Motor Current Max = 60A Motor Current Max Brake = -10A Absolute Max Current = 100A Battery Current Max = 50A Battery Current Max Regen = -15A Control Type Current No Reverse Brake ADC2 Gear Ratio = Direct Drive ON Wheel Diameter 255mm Motor Poles = 30 Battery Cells Series = 16 This jerking is more obvious when slowly changing from accelerating to braking however it can also appear when switching from braking to accelerating however it is frequently less noticeable when doing this. **Actually I have sets max brake -60A , regen -15A. 18 with 6S battery with 2 different type 190KV BLDC motor. 13680 changzhou geema friction materials co. How do you disable regen brake, or braking of any kind? My application needs to be able to coast when its in neutral. Working great! I have configured an analog throttle on ADC1 and analog brake on ADC2. Motor Tutorials. I have flipsky 4. 06 (5. 10950 brembo s. how can i stop this option and let my motor spin freely with wheel after i release my throttle. 1: Done: 3. My car has 4 of these motors with 4 vescs controlled through can bus. Link to forum Fully programmable (using tools like VESC Tool). Actually connected is a 3-Wire Thump throttle To COMM with VCC-GND-ADC1 VESC regenerative braking and BMS . Brake sensors (power switch off) thumb throttle only working when PAS active; Software which will use upp 1000 Watt up to 8km/h and 250 Watt when over 20 km/h. 6 Ohm = 7. The only problem is that I only have forward and brake and no reverse. Or can the VESC dissipate braking energy via heat? Im a little confused as there is a negative ‘current brake max’ setting and a battery ‘max regen’ option. PAS with ADC works only when You are using brake switch, at least that was problem in my case. But I am a bit surprised that the VESC can't be tuned up to fit better the actual spec of the motor/gear/prop assembly. VESC is controller/master. The result function should be something like: "Braking Demand" = "Brake potentiometer" + "speed" (ERPM) * "Braking Speed Gain constant" (when "Brake potentiometer" > 0) I feel that using the regenerative braking is a bit unstable in slopes, specially when the battery has a maximum charging value. Sometimes, it brakes strongly & instantly, sometimes, there is a delay (~200-500ms) with really low braking force (even if brake is pressed at max during This is the source code of the VESC Braking Resistor firmware. The VESC can neither store this energy nor dissipate it - all it can do is transfer it on to the battery. [PSU] -----<X>-----[VESC]-----[BLDC] Where the VESC is controlled by a modded servo tester with a potentiometer pedal. Hi, I built my e-skate and i have mapped my vesc with your vesc tool. In "pid speed no reverse" mode (helicopter application), when the servo reach 0, I have a strong brake of the motor. page. This results in a better behaviour than checking only motor current of local As a brake pads manufacturer focusing on after market in North America, all our products have passed SAE J661 testing in authorized testing laboratory and are on AMECA compliance list of VESC V-3 brake Friction Material. 05FW) Part2:Ubox Fimware All Ubox model FW of different version can be downloaded from github. currentCallback() Brake Friction Material Certification for the General Public: Download our FAQ document with the most recent AMECA information, revisions, and changes. In this page, the control type behaves as expected, with "Current No Reverse Brake ADC2" being the correct choose for two separate inputs to control acceleration and brake. The PCB is designed using KiCad. I have to pedals. VESC Bible. There is also a timeout brake current that can be configured on that page that can be used to brake the motor when timeout occurs. Link Engineering Co. The brakes didnt stop the board during this 10 seconds as it flew off and did a few flips into the bush and they wheels kept spinning until the 10 seconds was up. Mini USB is used for HW 4. Should this work as a fail safe when, for example, the battery of my remote control dies? VESC V-3 Brake Friction Material VESC V-5 Trailer Hitches; AMECA exists to serve you and the motoring public. ADC Control Introduction VESC ADC Mode (ADC&ADC2) As picture shown above, our vesc provides two interfaces, ADC and ADC2. AMECA has all VESC Files. Current MIN is the value that is used during braking/regen (storage of energy Timeout brake in case of connection loss to remote. number of motor 2. We are also registered What did you set the motor current limit to for regen? How fast are you going when you try to brake? The brake doesn't do much at low speeds. IE: If you have the throttle fully twisted, the VESC will push the bike to max speed. Each CAN node has a unique ID, the ID determines the priority (ID 0 is most dominant). This is what Benjamin Vedder has said about the topic: From VESC Node 398 - There is no way to brake in a controlled way without pushing the current back into the battery. VESC Project. I have 2 high discharge lipo batteries which combined gives 48 V, VESC 75/300, an Flipsky61461 waterproof motor and a small Flipsky 5062 to play with. 05(6. 30: 2017-11-06: PID handbrake at full brake option when sensors are present. I believe that when this mode is set and the PPM input is less than the center the controller will give a current set point proportional to the PPM position. im using a flipsky 75100 on a 14" bike that has disc brakes. 0(5. a. We offer an FAQ, a "Public Materials Listing" on our AMECA Web Portal, and our info@ameca. Please make option to apply current to active brake motors when speed slow and motor generate less power. We will use a PPM signal Just can't find info how to activate e-brake on e-scooter with the throttle. I had recently purchased Flipsky 75200 Pro v2. VESC Canbus Communication¶ A CAN Bus frame can contain a maximum of 8 bytes of data. I'm using the Arduino Nano ESP32 as a communication nexus of sorts between the BLE/dash and the VESC board. -25A becomes -12. My problem is that now my brake is just not working after 1 or two seconds of trying to brake (I figured it's because it passes the max current), Most hobby ESCs have duty cycle mode implemented without active freewheeling, so setting a lower duty cycle than the current motor back emf will not cause any braking (braking is actually not possible at all with that kind of modulation, so they use a completely different braking mode which makes terrible noise and is very inefficient). There are three main tasks handled by the board: Via I2C, receive updates on motor and battery status from the VESC board, send updates on throttle/brake/etc. (sometimes scary) : when I press full brake, it never react the same way. The braking torque, in that case, is certainly lower compared to the braking torque when you press the full break pedal. 2FW) Version 6. Workaround: Use "Current I am using the Spintend VESC 75/100 v1 (FW 5. VESC Tool wise, it would be more complicated as it will require to check the consistency of user choice (for instance, disabing Rx/Tx mapping if UART activated). 59 to 3. Help your project succeed through the power of collaboration and the combined knowledge of the VESC community. The conventional ADC controller has three leads(VCC, GND, ADC). I have a VESC that attaches to a nano Arduino through the servo connector (which is attached to my scooter hall throttle). So far it's been great, I love the programmability and it seems to handle 12s just fine, however one thing I am concerned about it is the regenerative braking and my Lipo packs. Configuration of your VESC® or VESC® based ESC using the VESC®-Tool Software. Select VESC Project. hello everyone i am tauhid from Bangladesh. I am using the Flipsky FSESC6 for each motor, a generic 170KV 6374 motor as the driver, and a 130KV Flipsky 66112 motor as the generator (need a waterproof Avenida Jaragua, 89 (Setor L), Bairro Aparecida, Sorocaba, SP, CEP 18087-380 Brazil If possible connect the two DC busses, lose the resistor bank. If the duty cycle is 0 then how do I read some non-zero erpm. Expand submenu Support I am using MKS and FlipSky 50A VESC to control 350W 24V DC motors. But the load is indeed limited to say 50V / 6. And how much of the 60A eaten to charge the battery? If Battery Current Max Regen=20, then 20A is sent to the battery. May I ask what is your "Battery Current Max Regen" setting value? If by 20A brake current, you mean -20A "Motor Current Max Brake", I would suggest you to start from -50A, and try to decrease the value further, up to the VESC's This video shows how to connect throttle and brake to our FSESC and how to do parameters setting in VEST. In short, the controller tells the motor how hard to push or how strong to brake. The maximum I can get is around -2. The document is an AMECA compliance list that provides information on brake friction material manufacturers and their approved product markings for the years 2014-2017. I would like to have some special algorithm of current limitations. 5A @ Hi, has anyone used a resistor to help brake the motors through the VESC? My plan was to wire the resistors in parallel with the power supply and use an electronically controlled transfer switch to switch over to the resistors and use the regen braking function. In "current mode no reverse", there is not his problem, current and duty seems always positive and I can stop more quickly without active braking.
