Message value: -
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Component: Control Unit (CU) Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The "Safe Torque Off" (STO) function of the basic functions has been selected on the Control Unit (CU) using the
input terminal and is active.
Note:
- this message does not result in a safety stop response.
- this message is not output when STO is selected using the Extended Functions.
Remedy: Not necessary.
Note:
CU: Control Unit
SI: Safety Integrated
STO: Safe Torque Off / SH: Safe standstill
Reaction upon F: OFF2
Acknowl. upon F: IMMEDIATELY (POWER ON)
Reaction upon A: NONE
Acknowl. upon A: NONE

Message value: -
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Component: Control Unit (CU) Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The "Safe Stop 1" (SS1) function has been selected on the Control Unit (CU) and is active.
Note:
This message does not result in a safety stop response.
Remedy: Not necessary.
Note:
CU: Control Unit
SI: Safety Integrated
SS1: Safe Stop 1 (corresponds to Stop Category 1 acc. to EN60204)
Reaction upon F: NONE (OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
Reaction upon A: NONE
Acknowl. upon A: NONE
F01625 SI P1 (CU): Sign-of-life error in safety data
Message value: %1
Message class: Internal (DRIVE-CLiQ) communication error (12)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-integrated "Safety Integrated" function on the Control Unit (CU) has detected an error in the sign-of-life of
the safety data between the two monitoring channels and has initiated a STOP A.
- there is either a DRIVE-CLiQ communication error or communication has failed.
- a time slice overflow of the safety software has occurred.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
