F039 2 T Power Section Monitor Has Responded (Active In Operating States Of – –, I, Ii); F040 Electronics Supply Disconnected In Active Fault Status (Active In All Operating States); F041 Ambiguous Selection Of Parameter Set Or Ramp-Function Generator (Active In All Operating States) - Siemens 6RA70 Series Instructions Manual

Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
I 2 t power section monitor has responded
F039
(active in operating states of – –, I, II)
This monitoring function responds if the calculated I 2 t value of the power section reaches the permissible value for the power
section concerned (see also P075).
Possible fault causes
♦ Drive has been operating at overload for too long
♦ Parameter P075 is incorrectly set
♦ Parameter P077 is incorrectly set
F040 Electronics supply disconnected in active fault status
(active in all operating states)
This fault message is activated if the electronics power supply has been disconnected, even though a fault was displayed and not
yet acknowledged.
Possible fault causes
♦ Not all fault messages have been acknowledged
Fault value:
Last active fault message
F041 Ambiguous selection of parameter set or ramp-function generator
(active in all operating states)
♦ While an optimization run is in progress, the function data set selection must not be changed. Fault F041 is displayed if
another, different function data set is selected while an optimization run is being executed.
♦ Check whether ramp-function generator parameter set 1 or 2 or 3 (parameters P303 to P314) is clearly selected. If parameter
sets 2 and 3 are selected simultaneously for more than 0.5s, then fault message F041 is displayed. While the parameter set
selection is ambiguous, the system continues to apply the last clearly identified ramp-function generator parameters.
Possible fault causes
♦ P676 or P677 (selection of binectors which determine the active function data set in control word 2, bits 16 and 17) is
incorrectly set
♦ P637 or P638 (selection of binectors which determine ramp-function generator setting) is incorrectly set
Fault value:
2 The selection of the function data set has been changed during an optimization run
3 Ambiguous selection of ramp-function generator parameter set
