    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).

      If the motor fails to run after you've changed the parameters, try resetting the inverter to its factory default parameter values. To do this, set P0010 = 30, then P0970 = 1, and press P. After resetting, use a switch between terminals 1 and 4 on the I/O board; the drive should now run to the defined setpoint, which is established by the analog input and/or control potentiometer.
