Overview of Alarms
Remedy: Re fault value = 1 to 999:
- check the crosswise compared data that resulted in a STOP F.
- carry-out a POWER ON (power off/on) for all components.
- upgrade the motor module software.
- upgrade the control unit software.
Re fault value = 1000:
- check the wiring of the safety-relevant inputs (SGE) on the control unit (contact
problems).
Re fault value = 1001, 1002:
- carry-out a POWER ON (power off/on) for all components.
- upgrade the motor module software.
- upgrade the control unit software.
Re fault value = 2000, 2001:
- check the tolerance time SGE changeover and if required, increase the value (p9650,
p9850).
- check the wiring of the safety-relevant inputs (SGE) (contact problems).
- replace the motor module involved.
Note:
CU: Control unit
MM: Motor module
SGE: Safety-relevant input
SH: Safe standstill
SI: Safety Integrated
230620 <location>SI MM: Safe standstill active
Reaction: NONE
Acknowledge: NONE
Cause: The "safe standstill" function was selected on the motor module (MM) and is active.
Note:
This message does not result in a safety stop response.
Remedy: None necessary.
Note:
MM: Motor module
SI: Safety Integrated
230625 <location>SI MM: Sign-of-life error in safety data
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-based "Safety Integrated" function on the motor module (MM) has detected an
error in the sign-of-life of the safety data between the control unit (CU) and MM and initiated
a STOP A.
- there is either a DRIVE-CLIQ communications error or communications have failed.
- a time slice overflow of the safety software has occurred.
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):
Only for internal Siemens troubleshooting.
