30.12 M1FldMinTrip (minimum field trip)
The drive trips with
F541 M1FexLowCur [FaultWord3 (9.03) bit 8] if M1FldMinTrip (30.12) - in percent of
M1NomFldCur (99.11)
- is still undershot when FldMinTripDly (45.18) is elapsed.
Note:
M1FldMinTrip (30.12)
is not valid during field heating.
In this case, the trip level is automatically set to 50 % of
M1FldHeatRef (44.04).
The drive trips with F541 M1FexLowCur [FaultWord3 (9.03) bit 8] if 50 % of
M1FldHeatRef (44.04)
is still undershot when FldMinTripDly (45.18) is elapsed.

30.13 M1FldOvrCurLev (field overcurrent level)
The drive trips with
F515 M1FexOverCur [FaultWord1 (9.01) bit 14] if M1FldOvrCurLev (30.13) -
in percent of
M1NomFldCur (99.11)
- is exceeded. It is recommended to set M1FldOvrCurtLev (30.13)
at least 25 % higher
than
M1NomFldCur (99.11).
The field overcurrent fault is inactive, i
f M1FldOvrCurLev (30.13) is set to 135 %.

30.14 SpeedFbMonLev (speed feedback monitor level)
The drive reacts according to
SpeedFbFltSel (30.17) or trips with F553 TachPolarity [FaultWord4 (9.04)
bit 4]
if the measured speed feedback [
SpeedActEnc (1.03) or SpeedActTach (1.05)] does not exceed
SpeedFbMonLev (30.14)
while the measured EMF exceeds EMF FbMonLev (30.15).

Example:
With
SpeedFbMonLev (30.14) = 15 rpm and EMF FbMonLev (30.15)
= 50 V the drive trips when the EMF is >
50 V while the speed feedback is
≤ 15 rpm.

30.15 EMF FbMonLev (EMF feedback monitor level)
The speed measurement monitoring function is activated, when the measured EMF exceeds

30.16 M1OvrSpeed (overspeed)
The drive trips with
F532 MotOverSpeed [FaultWord2 (9.02) bit 15] if M1OvrSpeed (30.16) is exceeded. It is
recommended to set
M1OvrSpeed (30.16) at least 20 % higher than the maximum motor speed.
