6.2 Troubleshooting with the BOP

If the display shows a fault or warning code, please consult the Faults and Warning
section of the SINAMICS G110 Parameter List.
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 (see example on page 66).
Check that P0700 = 1 (for BOP control) or
Check that the setpoint is present (0 to 10V on Terminal 9) or the setpoint has
been entered into the correct parameter, depending upon the setpoint source
(P1000). See the Parameter List for further details.
If the motor fails to run after changing the parameters then:
1. Set P0010 = 30
2. Set P0970 = 1
3. Press
4. Use a switch between terminals 3 and 6 on the control board.
5. The inverter should now run to the setpoint defined by either the analogue
input or transmitted via the USS serial link communications.
