Hi, I am having an issue where, when I apply currents >~2A to one motor, the other motor moves. This specifically seems to happen when the current is changing (e.g., the motor moves when going from 0 to 2 A but seems to stay static if 2A stead-state are applied. The M0 motor movement only happens when I change current on M1. If I change the current on M0, M1 does not move.
A few things I’ve done:
-Swapping motors/encoders. I swapped all the motor leads and encoder pins to swap M1 and M0 and the issue persists. M0 moves when a current change occurs in M1, but not the other way around.
-I checked the brake resistor readings. I read about 2.3 Ohms from the multimeter when unplugged, and the
odrv0.config.brake_resistance is set accordingly.
-The motor movement seems to be independent of whether I do open-loop or closed-loop control (i.e., it’s not an issue with the encoders.
Thanks a lot for the help!
