9.6 Servo Amplifier Response / Resolver
9.6.1 Code 5-0 SERVO AMPLIFIER REPLY ERROR / NO REPLY FROM RESOLVER
The controller is attempting to turn the motor, but is not receiving any signals back from the
resolver to indicate that the tool is actually turning.
This abnormal is caused from;
1. The motor/resolver cable is damaged or not connected
2. When the resolver, motor, or the controller malfunctions.
3. If there is excessive binding in the fastener, transmission, or the spindle assembly keeping
the motor from turning.
RECOVERY:
1. Verify that the motor cable is connected and not damaged.
2. Connect all spare tool cables to the existing tool.
3. Exchange tool and/or controller with known working units. Reinitialize the system after
exchanges.
4. Inspect and correct any binding in the spindle assembly, transmission or fasteners.
