Installation, Maintenance, Service & Part List Manual
3. Check all the wiring connections to the servo drive and motor.
4. Swap the X and Y axis motor. If problem stays with the X axis, then
replace the servo amp.
5. If the Z axis continues to fault, replace the servo or motor.
Intermittent Axis Fault 1. Identify the fault code on the axis that is intermittently faulting. Check
parameters P4-01 through P4-04 for a history of the most recent faults.
The nature of the axis fault will now dictate the direction you go from a
troubleshooting standpoint.
2. It is always a good idea to rule out a mechanical drive train issue.
Servo error 11 – encoder
error
Check cable connections, especially the encoder cable to the motor, both
ends of cable. If the cable was loose or had a poor connection, fix problem
and power off and back on the machine.
Servo error 1 -
Overcurrent
If mechanics check out OK, then remove axis belt and run motor with no load
to see if problem still exists. If it does, then swap the X and Y axis motors
and see if problem stays or goes. Based on the result, replace the motor or
servo.
For the Z axis, order a replacement motor and servo and replace only the
part that turns out bad.
5.6 Spindle Motor & Inverter
Danger!
The spindle motor and Inverter run from 415VAC. Use care when working with these components.
There is possibility of death by electrocution!
The inverter stores energy after power is removed. Allow 5 minutes for the energy to dissipate before
servicing. The charge light (behind the front cover) goes out once energy is dissipated to a safe level.
5.6.1 Spindle Motor
The spindle motor is a 2.2kW induction motor rated for a max rpm of 6000 rpm. The spindle motor
contains a 1024 window encoder that produces 4096 counts per revolution; attached to the back of the
motor. The spindle motor directly drives the spindle via a coupling. The spindle motor also contains a 110
VAC fan that is used to cool the motor. The fan blows air down over the motor.
WARNING!
Whenever the spindle motor is replaced or removed, service code 510 must be performed to reset the
orientation angle. Also check tool change positions in service code 520.
Symptoms Diagnostics
Spindle goes to the
wrong orientation angle
when doing a tool
change.
1. Verify that the spindle count on parameter 10-19 is set to the same value
as the spindle orientation counter under service code 510.
2. Check for spindle motor coupling being loose or slipping.
3. Redo the spindle orientation setup.
Spindle faults out
immediately when
trying to run the
spindle.
1. Verify that the spindle encoder is working properly. Use service code 510
to check.
2. Verify that the Inverter parameters have the correct values.
3. Verify that the spindle is able to turn freely.
4. Verify that the spindle power wiring is correct and properly fastened.
1. Verify that the deceleration parameter (01-13) on the inverter is set
correctly.
