Fault tracing
Cause
The motor configuration
parameters are set incorrectly.
The drive is not dimensioned
correctly.
The settings of drive-to-drive
link configuration parameters
(group 57) are incompatible.
Motor is operating in stall region
because of, eg, excessive load
or insufficient motor power.
No speed feedback is received.
Communication between drive
and option module (FEN-xx
and/or FIO-xx) is lost.
The voltage of the intermediate
DC circuit has not yet risen to
operating level.
Speed controller autotune
routine did not finish
successfully.
Low voltage mode has been
activated but the parameter
settings are outside allowable
limits.
Encoder 1 is receiving too high
data flow (pulse frequency).
What to do
Check the settings of the motor configuration
parameters in group 99.
Check that the drive is sized correctly for the
motor.
Check the settings of the parameters in group
57.
Check motor load and drive ratings.
Check fault function parameters.
Check the settings of the parameters in group
22.
Check encoder installation. See the
description of fault 0039 (ENCODER1) for
more information.
Check encoder cabling. See the descriptions
of alarms 2031 (ENCODER 1 CABLE) and
2032 (ENCODER 2 CABLE) for more
information.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To determine
whether module or connector is damaged:
Test each module individually in Slot 1 and
Slot 2.
Wait for the DC voltage to rise.
See parameter 28.16 PI TUNE
Check the Low voltage mode parameters in
group 47. See also section
on page 48.
Check encoder settings.
Change parameters 93.03 ENC1 SP
CALCMODE and 93.13 ENC2 SP
CALCMODE to use only one channel pulses/
edges.
