What to do if none of the LEDs light and Siemens SIMATIC SIMOSTEP 1FL3041 motor doesn't rotate?

If none of the LEDs light up, and the Siemens Servo Drive motor doesn't rotate or have holding torque, check the mains voltage and wiring to ensure they are properly connected. Also, verify that the PWM input is set to inactive. Finally, with the mains voltage disconnected, inspect the motor wiring for any interruptions.
