We have a Victor SPX that does not appear to be outputting any voltage above 1.8 volts.
This started on our 4 motor drive system (KoP 2 CIMs per side) which has 4 Victor SPXs controlled via CAN. We tried disconnected one motor on each side just to verify that everything was working (not expecting to find any problem) and ending up isolating this Victor. We tried connecting a known working motor to it and connecting a working Victor SPX to the motor that hadn’t worked. The results both pointed to this Victor being bad. The LEDs indicate it is getting the expected signal.
We pulled the Victor out of the robot and connected it to a known working prototyping setup which has a PWM generator controlled with a knob and the Victor still did not work. When we used a volt meter, the most we could get out of it was 1.8 volts but it was VERY inconsistent.
The firmware on all our CAN devices have been updated recently. I don’t have the version in front of me but it was downloaded within the last couple weeks.
What is our next step?
