S120 infeed error when trying to enable.

timberman Posts: 1 Rating: (0)	Hi all, Im trying to configure a s120 setup with the CU320 control unit and a 20kw (6SL3130-1TE22-0AA0)infeed and have a problem when commissioning. When control priority is assumed and I try to switch the infeed on im getting this error after 30 secs of waitingwhen Infeed is building up dc linkage. The error:''The maximum waiting time for bulding u the DC link voltage has elapsed. The infeed control priority has been returned''. After the errorthe control unit goes offline again as well. I have voltage on the DC linkage, about 540 volts. Also I dont have any other alarms when going online, the only warning it states is that the motor data identification is activated. Anyone knows whats causing it to not build up my dc linkage? Thanks in advance!
