APPENDIX C. Troubleshooting
C.1 Connections
If the motor does not rotate check that the connections are correct. Refer to the circuit
diagrams and maintenance instruction AS-11.65.020.
C.2 Drive fault codes
Check the connection of connectors XSR1
(safety relay input) and
XM1 (MLB
Interface) on HCB board.
Refer to the circuit diagrams.
If you have to change the connection of the
connector XSR1 (safety relay input) or XM1
(main contactor supervision), switch the
power off.
The new connection will be valid after
power up.
One example of the connections:
Safety relay connection is not used.
Main contactor (A) is supervised.
XSR1 is overconnected. Set the value of
parameter
(6_38) to 0, 1, 2, or 3.
