Siemens F01951 fault code meaning
Siemens / F01951
Series: DCM-6RA80
CU SYNC: Synchronous application cycle missing
DC drive
Meaning: When DRIVE-CLiQ components with different application cycles run on a DRIVE-CLiQ socket, they must be synchronized with the control unit. This synchronization failed.
Possible causes
Source: SINAMICS DCM, Parameter Manual, firmware version 1.5 SP2 (based on 5.1 SP2) P986
Series: G110M, G115D, G120-CU240B-E-2, G120C, G120D
CU SYNC: Synchronous application cycle missing
converter
Meaning: Internal synchronization of the application cycle failed.
Possible causes
Source: SINAMICS G110M P691; SINAMICS G115D P748; SINAMICS G120, Control unit CU240B-2_CU240E-2 P723; SINAMICS G120C P666; SINAMICS G120D Control unit CU240D- 2_CU250D- 2 P857
Series: G120-CU250S-2
CU DRIVE-CLiQ: Missing synchronous application cycle
converter
Meaning: When DRIVE-CLiQ components with different application cycles run on a DRIVE-CLiQ socket, they must be synchronized with the control unit. This synchronization failed.
Possible causes
Source: SINAMICS G120, Control Unit CU250S-2 P1342
Series: G130-G150, S120-S150
CU SYNC: Synchronous application cycle missing
converter
Meaning: When DRIVE-CLiQ components with different application cycles run on a DRIVE-CLiQ socket, they must be synchronized with the control unit. This synchronization failed.
Possible causes
Source: SINAMICS G130_G150 P1559; SINAMICS S120_S150 P2668
Series: G200, G210, G210X, G220
Application cycle synchronization missing
converter
Meaning: When DRIVE-CLiQ components with different application cycles run on a single DRIVE-CLiQ interface, they must be synchronized with the converter. This synchronization failed.
Possible causes
Source: SINAMICS G200 converter P686; SINAMICS G210 converter P1078; SINAMICS G210X converter P940; SINAMICS G220 converter P1285
Series: S220
CU SYNC: Synchronous application cycle missing
converter
Meaning: When DRIVE-CLiQ components with different application cycles operate on one DRIVE-CLiQ interface, they must be synchronized with the control unit. This synchronization has failed.
Possible causes
Source: SINAMICS S220 converter P2195
