Hi,

On my multi-motor system, the winder motor work on torque mode, that’s means that with high speed reference and a low current limit, the motor is not running, stalled.

But the first problem is the fault 7902, it appears immediately the motor not run.

And the second problem is a no torque control on motor shaft.

The parameter P2175 is set to 0

The selected mode is P1300 = 20   (Without encoder

The CU320-2-PN

It is possible work on torque mode without encoder?

What are the parameters involved on this mode?

Thanks a lot
