VESC Tool

read RPM over CAN

Hello, 

we´re trying to build a speedometer over CAN massages. 

We set the CAN Baud to 100K and the CAN Mode to Comm Bridge but our CAN analyser only reads Errors.

Is there a setting mistake?

If there is an easier way to build such a speedometer with RPM, please let me know. ;)

We´re using an VESC 6 MK 4.

How to read COMM_ROTOR_POSITION through uart

Hi,

I'm setting to up communication to teh VESC through an Arduino. Using SolidGeek's libraries, I have been able to send position control commands. What I need, is to read in the current position of the motor.

In order to set position, I modified the existing "setRPM" to make a "setPOS" command.

To set position, I naively tired to convert "getVescValues" to a "getVescPos", with the command value of "COMM_ROTOR_POSITION". But this does not seem to be recognized (payload size is zero).

Problem with VESC Tool vs BLDC FW version

I just built VESC Tool for Linux from source, but no matter what FW I upload, VESC Tool thinks it is "a bit old" and tags it with "limited functionality" which means the Motor Setup Wizard just sends me back to firmware upgrade again and again.

I have tried using "FIRMWARE_default" with hw60_mk5 from VESC Tool v 3.01 test version 1 and 12 and even after upgrading to this firmware the tool says it is too old.

(I have also build the 5_03 dev branch FW and uploaded under "Custom" with same result.)

What am I missing?

no effect on set erpm/speed limit

Hi, 

I have the problem that when i set the speed limit in the profiles tap and set it to "use until Reboot OR Use permanently"

this setting is completely ignored and i got always max speed.

Here are my setup:

Vesc 100/250 @16s FW.:5.2

8Kg 10 pole inrunner

1:7,6 Gear ratio 

Wheel Daimeter 640mm 

I have set everything up again several times without success

I am at the end of my knowledge.

Motor whine with HFI?

Submitted by christopher.h.poole on Mon, 2021-04-19 15:49

I'm running two sensorless motors with the FOCBOX in HFI mode. Controlling the speed via ADC in PID speed control (reverse button).

HFI is working great to start from a stand-still, but the motors have a continuous loud whine from HFI even when there is zero throttle. Is there a way to configure HFI to disable unless a throttle is applied?

Overheating protection, voltage-/current-limitation etc.

Hello people,

Im currently using VESC to control a motor that translates its rotatory motion into translational motion so I can move parts from left to right and vise versa.

I wonder why its seems that VESC limitates the total current to about 20A. There is no "current-barrier" in the settings.
