N30620 (F, A) SI MM: Safe Torque Off active
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The "Safe Torque Off" function was selected on the Motor Module (MM) via the input terminal and is active.
Note:
This message does not result in a safety stop response.
Remedy: None necessary.
Note:
MM: Motor Module
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
N30621 (F, A) SI MM: Safe Stop 1 active
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The "Safe Stop 1" function (SS1) 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
SS1: Safe Stop 1 (corresponds to Stop Category 1 acc. to EN60204)
Reaction upon F: A_INFEED: OFF2
SERVO: OFF3
VECTOR: OFF3
Acknowl. upon F: IMMEDIATELY (POWER ON)
Reaction upon A: NONE
Acknowl. upon A: NONE
F30625 SI MM: Sign-of-life error in safety data
Drive object: All objects
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.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - select Safe Torque Off and de-select again.
- 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
