TROUBLESHOOTING AND COMPONENT REPLACEMENT

Kaaaw sk

6. Malfunction of the motor.

7. Servo spot weld gun:

–Clamping pressure and/or clamping time is excessive.

–Distance between weld points is short; the motor does not have time to cool suffi-

ciently between welds.

–Clamping pressure setting exceeds the servo gun motor power capacity.

⇒

Check the cyclo reduction unit, the gear, or the bearing(s) for mechanical failure.

Replace as necessary.

⇒

Re-teach the robot motion as necessary.

⇒

Check the harness and servo unit for electrical malfunctions and replace if necessary.

⇒

Replace the 1KB board.

⇒

Replace the 1KQ/1NR board.

Servo Spot Weld Gun

⇒

If the weld points are close to each other, set a time delay. This provides a cool-down

period for the servo gun motor.

⇒

Set the clamping force lower (see servo gun manufacturer’s specifications).
