8.2.8 Err-8_ Overvoltage
Supply voltage is too high or
unstable
Use voltmeter to check whether input voltage at
main circuit is normal
The motor brake frequently
and the brake resistance is not
connected
Connect the brake resistor
Failure of motor brake
resistor
Check the resistance of the resistor
Replace the brake resistance with a new one
Repair or replace the servo drive with a new
one
8.2.9 Err-9_ Under voltage
No input voltage at main
circuit.
Use voltmeter to check whether input voltage at
main circuit is normal
Rewiring according to operation manual.
Rewiring according to operation manual
Failure of main circuit
connector
Replace the connector with a new one
Supply voltage is too low or
unstable
Use voltmeter to check whether input voltage at
main circuit is normal
Repair or replace the servo drive with a new
one
8.2.10 Err-10_ Motor (IR
2
) overheat protection
Wrong wiring of the power
cable (U, V, W, PE)
Rewiring according to operation manual
Wrong wiring of the encoder
cable.
Rewiring according to operation manual
Check the encoder cable according to the
wiring diagram
Repair or replace the cable with a new one.
Restores the default parameter of the motor
Incorrect gain parameters
setting
Restores the default parameter of the motor and
adjusts gain parameters according to the
operation manual.
Check the mechanical connection
Improve the mechanical transmission parts
Check if the motor output torque is too large
Increase the capacity of the driver and motor.
Set up longer acceleration/deceleration time.
Lower the load
Power capacity is not enough
Check power specifications
Use three-phase power supply
Measure the resistance among the motor power
terminal U,V,W and PE
Repair or replace the servo motor with a new
one
Repair or replace the servo drive with a new
one
