I use S7-1516 PLC and four G120C drives (connected via profinet). They were working just fine until TIA Portal and the PLC crashed and I had to format the memory card of the PLC. I got the PLC working again but the drives won't work properly. The motors get "On/Off" signal (you can hear the high frequency noise when the "On" signal is given. But motor won't turn. Although the reference speed is being sent via the standard telegram. I did the factory reset to one of the drives and loaded the configuration again but nothing happened. It all stayed the same.

I also tryed to run the motor from commissioning-> control panel. It showed feedback which was 3 amps and 0.0 Hz..... .

Any ideas?
