8.2.5
Err-5_Encoder counter missing error
Probable causes
Conforming method
Measures
Encoder disconnected
Check if the encoder is connected or not
Connect the encoder with drive
Wiring error
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
Communication error caused
by interference
—
①
Separate the encoder cable and the power
cable if they are bound together
②
Use shielded twisted wire
Incorrect installation of
encoder
—
Reinstall the encoder
Failure of encoder
—
Repair or replace the servo motor with a new
one
8.2.6
Err-6_Overcurrent protection of power module
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 adjustment
—
Restores the default parameter of the motor and
adjusts it 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
Input command error caused
by interference
Use the internal command to test the machine
①
Separate the input command cable and the
power cable if they are bound together
②
Use shielded twisted wire
Communication error caused
by interference
—
①
Separate the encoder cable and the power
cable if they are bound together
②
Use shielded twisted wire
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 encoder
—
Repair or replace the encoder with a new one
Failure of servo drive
—
Repair or replace the servo drive with a new
one
8.2.7
Err-7_ Main circuit relay disconnected
Probable causes
Conforming method
Measures
Power supply disconnected
Use voltmeter to check whether input voltage at
main circuit is normal
Rewiring according to operation manual
Supply voltage is too low or
unstable
Use voltmeter to check whether input voltage at
main circuit is normal
Use a regulator
Failure of motor
—
Repair or replace the servo motor with a new
one
Failure of servo drive
—
Repair or replace the servo drive with a new
one
