Code A08-16 - SERVO AMPLIFIER ERROR / MOTOR DRIVE POWER VOLTAGE ERROR
The motor three phase AC input power to the MFC Unit is disconnected or was turned off during
fastening.
CAUSE:
1. The controller internal power supply has failed.
2. The input power cable is not connected or is damaged.
3. Source voltage is out of the limit (180-253 VAC 3 phase).
4. One or more phases of input power are missing.
RECOVERY:
1. Verify that the input power cable is connected and not damaged.
2. Verify and correct the source voltage as required (on all three phases)
3. Verify whether the transformer is sized correctly
4. Replace the controller.

Code A08-17 - SERVO AMPLIFIER ERROR / SYSTEM CPU ERR
The controller has detected a failure of the Servo CPU
CAUSE:
1. The Servo CPU has failed
RECOVERY:
1. Replace the controller
•
Code A08-20 - SERVO AMPLIFIER ERROR / CURRENT SENSOR ERROR
The controller has detected a failure of the Servo Current Sensor
CAUSE:
1. The Servo Current Sensor has failed.
RECOVERY:
1. Replace the controller
•
Code A08-21 - SERVO AMPLIFIER ERROR / MOTOR HUNTING DETECTION ERROR
Motor oscillation is detected during fastening (detects CCW rotation during CW command and vice
versa). This function added at firmware version 1.417
CAUSE:
1. Deterioration of the servo isolation amplifier circuit due to use, duty and heat over a long
period of time (typically more than 15yrs.) may cause sensing of incorrect motor current draw
which leads to larger torque scatter and accuracy variance (greater than controller specified
accuracy)
2. Tool mounting may be loose, long spindles / extensions or external gearing (with large
‘wind-up’ causing backlash at high torques) are used
RECOVERY:
1. Turn off power to the controller for at least 5 seconds, then re-apply power.
2. Confirm tool mounting bolts are tight.
3. Adjust system parmeter (054) higher until abnormal condition ends (if caused by #2 above)
4. Replace the controller if fault continues.
Note: Limit value for this detection is set in System Parameter “SYS_054”. Factory set value is 25000.
Can be adjusted up to 999999 if false alarms are occurring.
See 8-4-3 for system parm. setting method
