Remedy: Motion monitoring not enabled (p9501 = 0):
- select safe standstill and then de-select again.
Motion monitoring enabled (p9501 > 0):
- carry-out a POWER ON.
Independent of the motion monitoring enable:
- carry-out a POWER ON (power off/on) for all components.
- 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.
- de-select all drive functions that are not absolutely necessary.
- reduce the number of drives.
- check the electrical cabinet design and cable routing for EMC compliance
Note:
CU: Control unit
MM: Motor module
SI: Safety Integrated
230630 <location>SI MM: Brake control defective
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-based "Safety Integrated" function on the motor module (MM) 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 or the control unit is faulty.
- a DRIVE-CLiQ communications error has occurred between the control unit and the
motor module.
Note:
This fault results in the following safety stop response dependent on p9501:
- Motion monitoring not enabled (p9501 = 0) --> STOP A that can be acknowledged.
- Motion monitoring not enabled (p9501 = 0) --> STOP A that cannot be acknowledged
(POWER ON).
Fault value (r0949, decimal):
10: No brake connected or fault in the motor module brake control circuit ("open brake"
operation).
30: Short-circuit in the brake winding or fault in the motor module brake control circuit
("close brake" operation).
40: Defect in the brake control circuit of the motor module ("brake closed" state).
60, 70: Fault in the brake control of the control unit or communications fault between the
control unit and motor module (brake control).
Remedy: Motion monitoring not enabled (p9501 = 0):
- select safe standstill and then de-select again.
Motion monitoring enabled (p9501 > 0):
- carry-out a POWER ON.
Independent of the motion monitoring enable:
- 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.
