Chapter 9 Troubleshooting
Output-to-ground
short-circuit
The power output
cables (UVW) of the
servo drive are short
circuited to ground.
Disconnect the UVW
cables from the motor,
and measure whether
the motor UVW cables
are short circuited to
ground.
Connect the cables again or replace
them.
The motor is short
circuited to ground.
Disconnect the UVW
cables from the motor,
and measure whether
the motor UVW cables
are short circuited to the
motor grounding wire.
Abnormal ASIC
communication
Restart the drive, the fault cannot be
reset, replace the drive.
Incorrect
interpolation
period
P20.10 sets an invalid
interpolation period
Query master station
synchronization period
and interpolation period
When the synchronization period of
the master station is consistent with
the interpolation period, P20.10 is
set to zero. When it is inconsistent,
P20.10 is the same as the
interpolation period of the master
station.
The given
position
instruction of the
controller is too
large.
The given position
instruction of the
controller is too large.
Confirm controller
position instruction given
Reduce the given deviation of the
controller position instruction.
Synchronization
signal lost
No synchronization signal
was detected after
entering the OP state
Check the DC
configuration of the
controller
Electronic gear
ratio error
The electronic gear ratio
is set incorrectly.
Confirm whether the
electronic gear ratio
parameter setting is
reasonable.
Correctly set the electronic gear
ratio parameters.
