I have a communication problem on the Atlas Copco compressor between the Elektronikon 5 graphic front panel and the Masterdrive CUVC Siemens inverter. The problem appeared just after the drive was reset to factory settings via the parameter P970.

Is there a way to restore the old parameters or shall I ask Atlas Copco to send me the parameters file so that I download it into the drive by using the DriveMon software?

Any suggestions
