9.9

Servo Amplifier / Encoder cable

9.9.1 code 8-0 servo amplifier error / encoder cable is broken

The controller can not detect the presence of an encoder.

This abnormal is caused from only 2 items.
1. If the encoder cable is damaged or disconnected.
2. When the encoder or the controller malfunctions.

RECOVERY:
1. Connect the spare encoder cable to the existing tool.
2. Exchange tool and/or controller with known working units. Reinitialize the system after
each exchange, and make note of any change in the location of the abnormal.
3. Replace the defective component.

9.9.2 code 8-1 servo amplifier error / over current

Over current or servo type mismatch.

The servo amplifier does not match the connected motor type. Verify the servo type tag with
the motor type tag.

There are 4 type of servo amplifiers (controllers) available.

9.9.3 code 8-2 servo amplifier error / encoder abnormal

The controller can not detect the presence of an encoder.

This abnormal is caused from only 2 items.
1. If the encoder cable is damaged or disconnected.
2. When the encoder or the controller malfunctions.

RECOVERY:
1. Connect the spare encoder cable to the existing tool.
2. Exchange tool and/or controller with known working units. Reinitialize the system after
each exchange, and make note of any change in the location of the abnormal.
3. Replace the defective component.
