i want to ask you about a problem faced me with the simoreg 6RA70 drive. the drive in the machine is sent from supplier and he told me all the parameters are ready to run the DC motor with tacho.

but when i connected the drive to motor and operate the motor is not running. the shaft is continuously fluctuating (half cycle to right and half to left). the armature current is also fluctuating from 2 - 9 amperes (up and down) and strange sound is emitted from the drive in panel.

can you help me in this issue
