Fault tracing
Cause
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).
Encoder 2 is receiving too high
data flow (pulse frequency).
Brake chopper is configured
wrong.
What to do
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 45.
Check encoder settings.
Change parameters 93.03 ENC1 SP
CALCMODE and 93.13 ENC2 SP
CALCMODE to use only one channel pulses/
edges.
Check encoder settings.
Change parameters 93.03 ENC1 SP
CALCMODE and 93.13 ENC2 SP
CALCMODE to use only one channel pulses/
edges.
Check the brake chopper configuration in
parameter group 48.
