Jaguar stops powering the motor after a few seconds

[Itamar]

Hey,
We have a Jaguar connected to a cim motor with a transmission we made and to a sidecar module via PWM. The motor moves two axis. When we run it at any speed it works for a few seconds (not at constant intervals), stop, and after a few seconds starts working again.

We looked at the Jaguar's LED. When the motor is running the LED shows red value and when the motor stops it changes to yellow. We tried replacing a Jaguar and a PWM, but the problem persists.

I don't believe this is a software problem. I work with LabVIEW, and the code to power this Jaguar is very simple. Just in case, I called the "GetOutput" VI and the value is the same as sent, as expected. It never changes to zero, even when the Jaguar stops powering the motor.

We double-checked, the battery has over 12V.

What can cause this weird behaviour?

Thanks in advance,
Itamar.
