Let me start of by saying everything is working good via Profibus and all commands to the drive are working, ie Start/Stop, FWD, Reverse, the only thing that I can't get set is the Speed control, when i change the speed at the HMI it stays the same, no matter what speed i put. I see the drive when it energizes that it send out 9hz-22hz and that is it.
Motor is 460v 60HZ 1800RPM

any help will be greatly appreciated.

Oh, and the drive is a replacement and couldn't connect to the old drive, it is a direct replacement
