Code A08-10 - SERVO AMPLIFIER ERROR / OVER LOAD (I SQUARE T)
The servo amplifier has detected that the motor has drawn too much current over a predefined period
and has over loaded.
CAUSE:
1. The duty cycle of the fastening application is too severe for this size of tool or for the parameters
currently set up.
2. The servo amplifier is not getting proper feedback from the resolver and supplying extra current to
the motor.
RECOVERY:
1. Reduce duty cycle -
Increase tool “downtime or off time” and/or increase 1
st
,2
nd
and 3
rd
Speeds to
reduce the amount of time running at high torque/slow speed.
2. Increase the Ramp Down Start Torque, 1
st
Torque or 2
nd
Torque at which 1
st
Speed shifts to 2
nd
Speed.
3. If using Torque Recovery, try decreasing the recovery time.
4. Check the fastening joint. If it is a soft joint (increased angular turn) increase 1
st
Torque and/or
2
nd
Torque and speeds to keep motor from running slow (under load) for long durations
5. Check the cable connections.
6. If the problem remains, a larger tool assembly may be required for this application. Please contact
FEC.

Code A08-11 - SERVO AMPLIFIER ERROR / RESOLVER SIGNAL ERROR
The resolver signal received from the tool in the controller is not correct.
RECOVERY:
1. 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.
2. Confirm tool duty is below 60% and/or motor temp is below 70 degree C (158degree F)
3. Replace the tool.
4. Replace the controller
•
Code A08-12 - SERVO AMPLIFIER ERROR / SYSTEM ERROR
An internal system error has occurred.
RECOVERY:
1. Replace the controller.
•
Code A08-14 - SERVO AMPLIFIER ERROR / MOTOR PARAMETER ERROR
The internal motor parameters in the MFC Unit are abnormal or not correct for the tool.
RECOVERY:
1. Replace the controller.
•
Code A08-15 - SERVO AMPLIFIER ERROR / SYSTEM ERROR
An internal system error has occured.
RECOVERY:
1. Replace the controller.
