① U, V, W lead wires of
motor are not connected
correctly.
② Lead wires of encoder
cable are not connected
correctly.
① Connect them correctly.
① Encoder fault
① Change the servo motor.
① The orientation oversize
detecting setting range is too
small.
① Increase the setting range.
① The orientation proportional
gain is too small.
① Increase the gain.
① Torque is not enough..
① Check the torque limit
value.
② Reduce the load
capacity..
③ Change the driver and
motor with larger power
ones.
the motor doesn’t
rotate after switching
on the main power
supply and the control
wires and inputting
instruction pulse
① Instruction pulse frequency
is too high.
① Reduce the frequency.
① Circuit board is at fault.
① Change the servo driver.
Occurring in switching
on control power
supply
① Cable is broken.
② Internal temperature relay
of motor is damaged.
① Check the cable.
② Check the motor.
① Motor is overloaded.
① Reduce the load.
② Reduce the start-stop
frequency.
③ Reduce the torque limit
value.
④ Reduce the related gain.
⑤ Change the driver and
motor with larger power
ones.
Err-5
Motor
overheated
Occurring in motor
running
① Motor interior is at fault. ① Change the servo motor.
The motor is chucked
mechanically.
Check the mechanical part.
Err-6
Speed error
too big or too
long saturation
time fault of
speed
amplifier
Occurring in motor
running
The load is too big.
① Reduce the load.
② Change the driver and
motor with larger power
ones.
