Code A08-05 - SERVO AMPLIFIER ERROR / OVER VOLTAGE ABNORMAL
The MFC controller servo power supply circuit is not working properly or the input voltage is above
the maximum limit.
CAUSE:
1. The controller internal power supply has failed.
2. Source voltage is very close to the limit (253 VAC).
3. Internal regenerative voltage surge caused by motor ramp down.
RECOVERY:
1. Replace the controller.
2. Verify and correct the source voltage as required.
3. Reduce fastener rundown speed or reduce the difference between the fastener rundown speed
and ramp down speed.
4. Verify that rundown revolutions is not set too high (causing fastener to ‘slam’ into part before
slowing down)
5. Verify that the cable is not damaged. Replace if necessary.
•
Code A08-06 - SERVO AMPLIFIER ERROR / SOURCE VOLTAGE ABNORMAL
The MFC controller control power supply circuit has detected improper input power voltage either
above or below the specified limits.
CAUSE:
1. The controller internal control power circuit has failed.
2. Source voltage is out of the limit (24VDC +/-10%) and/or unstable.
RECOVERY:
1. Replace the controller.
2. Check the control power connections.
3. Verify and correct the source voltage as required.
•
Code A08-07 - SERVO AMPLIFIER ERROR / CONTROL POWER INTERRUPT ABNORMAL
The MFC controller control power circuit has detected input voltage below 18V.
CAUSE:
1. The control power supply (24VDC) does not have enough capacity.
RECOVERY:
1. Confirm power supply wiring
2. Change control power supply to a larger size.
•
Code A08-08 - SERVO AMPLIFIER ERROR / OVER SPEED.
The resolver signal received at the MFC controller indicates an over speed condition.
CAUSE:
1. The tool cable or resolver has failed.
RECOVERY:
1. Check resolver using method in 9-2-2.
2. Verify that the tool cable is securely connected at both ends and free from cuts, abrasive wear or
kinks. Replace tool cable with known good spare cable.
3. Replace tool assembly.
4. Replace the controller.
