Servo Amplifier Reply Errors [A.05 - *]
•
Code A05-01 - 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 or the speed reference on the amplifier is not responding.
CAUSE:
1. The tool 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.
4. System Parameter #523 (Fastening Current Limit) is not set to the correct value or set to 0% (may
be set too low).
5. Torque Transducer damage/error will not allow motor to start/turn.
RECOVERY:
1. Verify that the tool cable is securely connected at both ends and free from cuts, abrasive wear or
kinks
2. Connect a known good spare tool cable to the existing tool.
3. Exchange tool and/or controller with known working units. Reinitialize the system after exchanges.
4. Verify that System Parameter #523 [Fastening Current Limit] is set to the correct default value. (A
lower value than the default value will limit the current output of the controller to the value
programmed)
5. Inspect and correct any binding in the spindle assembly, transmission or fasteners.
