EnC9
Drive encoder trip: Position feedback is selected from a Solutions Module slot which does not have a speed / position
feedback Solutions Module installed
197
Check setting of Pr
3.26
(
Fb01, 0.71
)
(or Pr
21.21
if the second motor parameters have been enabled)
EnC10
Drive encoder trip: Termination overload
198
If the voltage from the encoder is >5V, then the termination resistors must be disabled (Pr
3.39
to 0)
Et
External trip
6
Check terminal 31 signal
Check value of Pr
10.32
Enter 12001 in Pr
xx.00
and check for parameter controlling Pr
10.32
Ensure Pr
10.32
or Pr
10.38
(=6) are not being controlled by serial comms
FbL
No feedback from the tachogenerator or encoder
159
If the difference between the estimated speed (Pr
5.04
) and the actual speed feedback (Pr
3.02
(
di05, 0.40
)) exceeds the value set
in the speed feedback loss window (Pr
3.56
) the drive will trip Feedback loss. With fast acceleration rates in applications with low
load intertia estimated speed (Pr
5.04
) may not track the actual speed feedback (Pr
3.02
(
di05
,
0.40
)) fast enough and the speed
feedback loss window (Pr
3.56
) may need to be increased.
Check the feedback device is connected correctly
Check motor name plate values have been entered into the drive correctly
Check the speed feedback in estimated speed mode - refer to running a motor section checking speed feedback
Carry out a rotating autotune
Fbr
The polarity of the feedback tachogenerator or encoder is incorrect
160
Check that the feedback devices are connected correctly
FdL
No current in the field supply circuit
168
Check that the field controller (Pr
5.77
(
SE12, 0.33
)) is enabled.
For the internal field controller check terminals L11, L12 are closed
Check internal auxiliary fuses, refer to section 4.6.3
FOC
Excess current detected in field current feedback
169
Maximum current feedback is present
Check Field rated current (Pr
5.70
(
SE10, 0.31
)) and Field rated voltage (Pr
5.73
(
SE11, 0.32
)) are set correct to motor nameplate
Check for short circuit on field circuit cabling
Check integrity of motor insulation
