1) If the trouble related to servomotor occur, alarm code is indicated on LED of front

panel.

2) At this time, servo motor power is OFF. For the release of the alarm, it is required that

procedure 1 [EMG Alarm: EMG -> STOP -> RESET -> READY] or procedure 2

[General Alarm: STOP -> RESET -> READY] is performed.

Caution For alarms related to power, turn off power and turn on

power.

3) For alarm caused by OVERLOAD, normal clear is possible in 10 seconds or more. So,

press the ‘READY’ button to supply power to the servo motor in 10 seconds or more

after pressing the ‘RESET’ button.

4) If troubles are caused by cable connection for the terminal of servomotor and improper

wiring, ensure that checking wiring is performed after motor power is off.

5) If the servomotor without mechanical problem does not drive, check if the parameter

is normal. And then if the same trouble ouccur again, replace the mortor drive.

6) If the drive of motor is not stable and acceleration/deceleration is improper, the

following checks should be performed;

Check if servomotor has mechnical problem

Check if servomotor parameter setup is normal

Check if the primary input voltage is acceptable

Check if the state of cable shield is normal.

7) The unmatched origins may be caused by serious difference between Z phase and

Home sensor or the defective axis board. So check the connections of axis board

cables.

8) The causes of noise are mainly noise, parameter, and bad connection of cable, etc.

except mechanical causes.
