8.2.8
Err-8_ Overvoltage
Probable causes
Conforming method
Measures
Supply voltage is too high or
unstable
Use voltmeter to check whether input voltage at
main circuit is normal
Use a regulator.
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
Failure of servo drive
—
Repair or replace the servo drive with a new
one
8.2.9
Err-9_ Under voltage
Probable causes
Conforming method
Measures
No input voltage at main
circuit.
Use voltmeter to check whether input voltage at
main circuit is normal
Rewiring according to operation manual.
Wiring error
Check the wiring
Rewiring according to operation manual
Failure of main circuit
connector
Check the 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
Use a regulator
Instantaneous power-off.
—
Use a regulator
Failure of servo drive
—
Repair or replace the servo drive with a new
one
8.2.10
Err-10_ Motor (IR
2
) overheat protection
Probable causes
Conforming method
Measures
Wrong wiring of the power
cable (U, V, W, PE)
Check the wiring
Rewiring according to operation manual
Wrong wiring of the encoder
cable.
Check the wiring
Rewiring according to operation manual
Failure of encoder cable
Check the encoder cable according to the
wiring diagram
Repair or replace the cable with a new one.
Wrong motor parameter
—
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.
Machine failure
Check the mechanical connection
Improve the mechanical transmission parts
Overloaded
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
Failure of motor
Measure the resistance among the motor power
terminal U,V,W and PE
Repair or replace the servo motor with a new
one
Failure of servo drive
—
Repair or replace the servo drive with a new
one
