decrease the environment
temperature
UVW output short circuit
or motor error
Change the motor, check the
UVW wiring
Motor speed is too fast,
motor UVW connection is
error
Check if there is external force
make the motor over speed,
check motor UVW connection
Input voltage is error when
two channels analog is
zeroing
Input correct voltage when
analog zeroing
Position offset is
too large
The difference between
setting value and actual
value is larger than limits
in position control mode
Check if the motor is blocked,
decrease the position setting
speed, increase the deviation
pulse limits P5-05
Motor UVW is
short circuit
External short circuit at
first power-on self-test
Check motor UVW connection,
change the broken motor
Current collection circuit
is error
Check motor wiring, change
servo drive
Not connect encoder,
encoder wiring is error or
damaged
Check encoder wiring,
re-connect it after power off,
change the encoder
Not connect encoder,
encoder wiring is error or
damaged
Check encoder wiring,
re-connect it after power off,
change the encoder
Speed changing is
too fast (encoder
feedback error)
Encoder wiring error,
encoder has external
interference
Check encoder wiring, add
shield layer for encoder wire
Run over load for long
time
Decrease the time of overload
running, change a motor with
larger rated power
