Hello, the trouble that We've got a few days ago is the next:

*ROBICON doesn´t obey STOP command from PROFIBUS, so we had to stopped from the emergency button.

*ROBICON doesn´t decelerate below 400rpm, it reach 1200 rpm (rpm nom=1792) like the minimun 

*The motor Inom=176A, ITOT=200A(drive current out) and we have at INPUT about 120A, I've connect a PC to the drive via TCP/IP and the results were: Ids doesnt follow property Ids reference, same case with Iqs 

and the Debug tool shows: Debug tool capture

We change the ISA BACK PLANE board and we solved the problem only for a week. I hope somebody give us any idea to atack this trouble.
Regards.
Darrent.

Dear Colleague,

the problem can be that you have load rotating the motor causing regeneration, whih cannot be absorbed by VFD. You can use Zero speed parameter (set it higher than 400rpm) or set the flag RampStop=FALSE is SOP.
