Troubleshooting with the Basic Operator Panel

Warnings and faults are displayed on the BOP with Axxx and Fxxx respectively.
If the motor fails to start when the ON command has been given:
Check that P0010 = 0.
Check that a valid ON signal is present.
Check that
Check that the setpoint is present (0 to 10 V on Terminal 7) or the setpoint has
been entered into the correct parameter, depending upon the setpoint source
(P1000). For further details see the Parameter List.
If the motor fails to run after changing the parameters, set P0010 = 30 then P0970
= 1 and press P to reset the inverter to the factory default parameter values.
By using a switch between terminals 1 and 4 on the I/O board, the drive should
now run to the defined setpoint (established by analog input and/or control
potentiometer).
