IMMEDIATELY (POWER ON)
The "Safety Integrated" function integrated in the drive on the Control
Unit (CU) has detected a brake control fault and initiated a STOP A.
– No motor holding brake connected.
– The motor holding brake control on the Motor Module is faulty.
– A DRIVE-CLiQ communications error has occurred between the
Control Unit and the Motor Module involved.
Fault value (r0949, decimal):
10: No brake connected or fault in the Motor Module brake control circuit
("open brake" operation).
11: Defect in the brake control circuit of the Motor Module ("brake open"
operation).
20: Short-circuit in the brake winding or fault in the brake control circuit of
the Motor Module ("brake open" state).
30: No brake connected, short-circuit in the brake winding or fault in the
Motor Module brake control circuit ("close brake" operation).
31: Defect in the brake control circuit of the Motor Module ("close brake"
operation).
40: Defect in the brake control circuit of the Motor Module ("brake closed"
state).
50: Defect in the brake control circuit of the Motor Module or communica-
tions fault between the Control Unit and the Motor Module (brake control
diagnostics).
Select safe standstill and then deselect again
– Check the motor holding brake connection.
– Check the function of the motor holding brake.
– Check whether there is a DRIVE-CLiQ communications error
between the Control Unit and the Motor Module involved and if
required, carry-out a diagnostics routine for the faults identified.
– Check the electrical cabinet design and cable routing for EMC
compliance.
– Replace the Motor Module involved.
