4 Faults and alarms
4.2 List of faults and alarms
For fault value = 2000, 2001, 2002, 2003:
- check the discrepancy time, and if required, increase the value (p9650/p9850).
- check the wiring of the F-DI (contact problems).
- check the causes of the STO selection in r9772. When SI Motion functions are active (p9501 = 1), STO can also be
selected using these functions.
For fault value = 6000 ... 6999:
Refer to the description of the message values in safety fault F01611.
For fault values that are described in "Cause":
- carry out a POWER ON (switch-off/switch-on).
- contact Technical Support.
- replace Control Unit.
Note:
F-DI: Fail-safe Digital Input
STO: Safe Torque Off
N30620 (F, A) SI P2: Safe Torque Off active
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: NONE
Cause: The "Safe Torque Off" (STO) function has been selected on processor 2 using the input terminal and is active.
Note:
This message does not result in a safety stop response.
Remedy: Not necessary.
Note:
STO: Safe Torque Off
N30621 (F, A) SI P2: Safe Stop 1 active
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: NONE
Cause: The "Safe Stop 1" function (SS1) was selected on processor 2 and is active.
Note:
This message does not result in a safety stop response.
Remedy: Not necessary.
Note:
SI: Safety Integrated
SS1: Safe Stop 1 (corresponds to Stop Category 1 acc. to EN60204)
F30625 SI P2: Sign-of-life error in safety data
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-integrated "Safety Integrated" function on processor 2 has detected an error in the sign-of-life of the safety
data and initiated a STOP A.
- there is a communication error between processor 1 and processor 2 or communication has failed.
- a time slice overflow of the safety software has occurred.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - select Safe Torque Off and de-select again.
- carry out a POWER ON (switch-off/switch-on).
- check whether additional faults are present and if required, perform diagnostics.
- check the electrical cabinet design and cable routing for EMC compliance
