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.
Servo Tool Type
AXIS 103 DFT-051M1,DFT-101M1,DFT-201M1,DFT-401M1
AXIS 105 DFT-201M2,DFT-401M2,DFT-601M3,DFT-801M3
DFT-132M3,DFT-202M3,DFT-302M3
AXIS 110 DFT-401W4,DFT-502M4,DFT-802M4,DFT-802W4
AXIS 120 DFT-153N1,DFT-203N1,DFT-403N1
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.
