Torque Error

in Robot Controller
Hello,

I have an IRB1600 mounted on linear track not ABB. This track is moved by MU20, I added a new drive unit DSQC_619_T to drive the motor.
I rebooted new system with new parameters with success but now, when the track moves, often these event messages happen:

- 39403 Torque Loop Undercurrent
- 39405 Maximum PWM Reached in Torque Controller


Mains supply voltage is ok and also motor configuration.

I don't know where is the problem.

Someone can help me????

    I had this problem too. I reloaded the moc file and the issue was resolved.
