11.3 Safety messages for SINAMICS S120
F01651 SI P1 (CU): Synchronization, safety time slices unsuccessful
Explanation The "Safety Integrated" function requires synchronization of the safety time slices between the two monitoring
channels and between the Control Unit and the higher-level control. This synchronization routine was not
successful.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, interpret decimal):
Fault value 121:
With SINUMERIK Safety Integrated enabled, a drive-side warm restart was executed on the CU/NX.
With SINUMERIK Safety Integrated enabled, on a drive object of the CU, the "Restore factory setting" func‐
tion was selected and a drive-side warm restart initiated.
Fault value 150:
Fault in the synchronization to the PROFIBUS master. All other values:
For Siemens internal fault diagnostics only.
See also: p9510 (SI Motion isochronous PROFIBUS master)
Remedy For fault value 121:
Carry out a common power on/warm restart for the higher-level control and SINAMICS.
For fault value 150:
Check the setting of p9510 (SI Motion isochronous PROFIBUS master), and if required correct.
Always:
Carry out a POWER ON (power off/on) for all components
Upgrade the Motor Module/Hydraulic Module software.
Upgrade the Control Unit software.
Upgrade the software of the higher-level control.
