08/2005
Cause: The drive-based "Safety Integrated" function in 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.
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).
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 communications fault between
the control unit and the motor module (brake control diagnostics).
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.
Note:
CU: Control unit
MM: Motor module
SI: Safety Integrated
201649 <location>SI CU: Internal software error
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: An internal error in the Safety Integrated software on the control unit has occurred.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry-out a POWER ON (power off/on) for all components.
- re-commission the "Safety Integrated" function and carry-out a POWER ON.
- upgrade the control unit software.
- contact the Hotline.
- replace the control unit.
