3.4 Initial commissioning
Danger to life if the motor unexpectedly moves during motor identification in the rotating
mode
When selecting motor identification with optimization in the rotating mode, after
commissioning, the drive initiates that the motor rotates with speeds that can reach the
maximum motor speed.
• Observe the general safety instructions.
• Ensure that the EMERGENCY STOP functions are fully functional when commissioning
Note
Activate enable signals
Make sure that the necessary enable signals have been assigned; otherwise motor
identification cannot be carried out.
Note
Fault with stationary or rotating measurements
If a fault is present when the stationary or rotary measurement is selected, motor
identification cannot be carried out.
Before rectifying the fault, you have to choose "No identification" and close the screen.
Motor identification can then be selected again via <MENU> - <Commissioning/service> -
<Drive commissioning> - <Motor identification>.
