Symptoms Diagnostics
Spindle will not perform a
spindle orientate command.
1. Verify that the orientation command is being sent to the AC drive by
measuring 0 VDC from MI3 to DCM terminals and from the FWD to
DCM terminals of the AC drive when the orientation command is
triggered (use service code 521)
2. Verify that the all the parameters are set correctly on the AC Drive.
3. Verify that the E-stop command to AC Drive has not been activated.
By measuring 0V from MI1 to DCM. When the E-stop command is
present it will measure 24V.
The AC Drive will fault out
immediately when starting
the spindle.
1. Verify that the spindle AC drive encoder PCB is properly seated.
2. Verify the spindle encoder on the motor works.
3. Verify that the wiring on the AC drive is correct.
4. Verify that the parameters on the AC drive are correct.
The AC drive has a Fault
which cannot be cleared.
Verify that the spindle Reset signal is being sent to the AC drive by
measuring the voltage between MI3 and DCM on the AC drive. When the
reset command is given, it should be 0 VDC and 24 VDC when no reset
command is given.
5.7 Electrical
5.7.1 Checking Voltages
DANGER!
Take extreme caution when working with high voltage. There is possibility of death by electrocution!
Only competent persons should undertake any electrical work on the machine.
There are eight voltages that can be checked when troubleshooting a system. A digital multi meter will be
necessary in order to measure the voltages. An auto ranging digital multi meter (DMM) is preferred with a
range of 0 to 600 VDC/VAC.
1. 415VAC, 3 phase: This is the main power to the machine; fed to the spindle motor and power/
control transformer only. Check voltages between each phase, as seen in
figure 5.7.1a.
