What to do if Siemens MICROMASTER 411 Inverter motor fails to start after ON command?

If the motor fails to start after the ON command, verify that a valid ON signal is present. Also, check that P0700 = 2 for Terminal I/O control or P0700 = 1 for BOP control. Finally, ensure that the setpoint is present (0 to 10 V on Terminal 7) or that the setpoint has been correctly entered into the appropriate parameter, depending on the setpoint source (P1000).
