The position
deviator overflow
① Motor is
mechanically
locked.
② Input instruction
pulse is abnormal.
① Check
mechanical part
of the load.
② Check the
instruction pulse.
③ Check whether
the motor runs by
instruction pulse.

is wrong.
Check the
connection.
Encoder is damaged. Change the motor.
Encoder cable is
inferior.
Change the cable.
9 Encoder fault
Encoder cable is too
long to cause the
encoder voltage too
low.
① Shorten the
cable.
② Use multi-core
parallel power
supply.
