I am getting these errors when i try to use a focbox and version 6.02:
"The connected VESC has newer firmware than this version of VESC Tool supports. It is recommended that you update VESC Tool to the latest version. Alternatively, the firmware on the connected VESC can be downgraded in the firmware page. Until then, limited communication mode will be used."
Hi,
I have an R/C car, it uses direct drive, so no transmission ratio. The motors (400kV) are set to use 40A on driving, it works like charm, the brake power is -25A and it's very weak. The max regen value is -5A but I'd like to reduce it to zero, because in the car I don't have any BMS. How can I achieve larger brake force? Increase the regen ampers? Thanks
Hey, the project I am currently working on requires multi-turn position control using ABI encoder, i.e., if I input +900° then it should make 2 complete turns and one half turn to stop at 900° = 720° + 180° in forward direction and if I input -900° then it should make 2 complete turns and one half turn to stop at -900° = -720° - 180° in reverse direction. If there is any feature available in any version or any firmware of VESC it would be great, I had tried a few things by myself but failed in task of implementing pid control for multi-turn.
Hi there,
I am trying to do some FW modifications and test some temperature-sensor related things.
So far, most things seems to work. I am able to build fw with for example "make 75_300_r2_no_limits". I am flashing the FW with a ST-Link directly.
It basically works and I am able to control the motor via the VESC-Tool, eg. current commands, etc. What does not work yet:
Hello everyone,
I've developed my own hardware based on the 75_300 design, with the only modification being the shunt resistor values. Originally, the design used 500uohm resistors in a 3-parallel configuration, but I've changed these to 400uohm resistors. Apart from this alteration, all other hardware components remain unchanged.
Hi guys,
Running a new VESC 6 EDU w/ stock firmware.
-> fwinfo
GIT Branch: release_6_03
GIT Hash : f7c2b34e
Compiler : 7.3.1
The default Zero Vector Frequency of 30 kHz has glitchy BEMF (sampled data graph) and runs rougher. 20 kHz is cleaner and quieter.
I am trying to first time program, it appears I need updated firmware but when I update I get an arrow message that the operation has been aborted because of a thread exit or application request. Any help would be great thanks
Hi All,
Hi all,
for my application I need to apply a rotating field to my machine at high currents. Basically exactly what the terminal command foc_openloop does.
Is there any way to control this via the CAN Bus? I am sure you can activate it via can, because it also works if the VESC is connected to VESC Tool via another Vesc over can but I am struggling to understand how the much more complex can forwarding seems to work.
