Fault
Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
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
F042 Tachometer
fault
(active in operating states of – –, I, II)
A check is performed every 20ms to ensure that
(K0287)
EMF
Actual
(K0179)
speed
Actual
is > +5%
If the check result is incorrect for 4 times in succession, the fault message is activated.
The following rule applies:
100% actual speed
= maximum speed
100% actual EMF
= ideal average DC voltage at
α
≥
0, i.e. when the thyristor bridge is fully gated
The ideal DC voltage average value at
α
= 0 is
π

P078.001

The monitoring function is effective only if the EMF > a % of
π
2
3
P078.001
∗
∗
"a" is a percentage that can be set in parameter P357 (default setting 10%).
The monitoring function is effective only if the armature current is > 2% of the converter rated DC current set in r072.002.
Possible fault causes
♦
Open circuit in tachometer or pulse encoder cable.
♦
Tachometer of pulse encoder cable incorrectly connected.
♦
Pulse encoder supply has failed.
♦
Polarity for actual speed value (P743) is incorrectly set.
♦
Armature circuit data (P110 und P111) are incorrectly set (execute current controller optimization run).
♦
Tachometer or pulse encoder defective
♦
Pulse encoder supply voltage is incorrectly set (P140)
♦
The field polarity is not reversed by the external hardware when the field is reversed.
Fault value:
r047 Index 002 to 016:
1
Open circuit in tachometer or pulse encoder cable
i002 Actual speed value (K0179) in case of fault
2
Polarity of tachometer or pulse encoder is incorrect
i003 Actual EMF value (K0287) in case of fault
