Siemens F041 fault code meaning

Series: 6RA70

Parameter settings or ramp-function generator selection are ambiguous.

DC drive

Meaning: (Valid in all operating states.) The function data set selection must not be changed during an optimization run. If a different function data set is selected during an optimization run, fault message F041 is displayed. If the parameter setting selection is ambiguous, the system continues to use the last unambiguously confirmed ramp-function generator parameters. Possible fault causes: P676 or P677 (binector selection defining the function data set activated by bits 16, 17 in control word 2) set incorrectly; P637 or P638 (binector selection defining the ramp-function generator settings) set incorrectly. 2 Function data set selection changed during an optimization run. 3 Ramp-function generator parameters.
