5-3-4 Troubleshooting the spindle system when there is no alarm or warning

If an abnormality is observed in the spindle system but no alarm or warning has occurred, refer to the

following table and check the state.

[1] No abnormality is displayed, but the motor does not rotate.

Investigation item Investigation results Remedies

The wiring is incorrect, the screws are

loose, or the cables are disconnected.

Correctly wire. Correctly tighten the

screws. Replace the cables.

Check the wiring around the spindle drive

unit.

Also check for loosening in the terminal

screws and disconnec- tions, etc.

No particular problems found.

Investigate investigation item 2 and

remedy.

The voltage is exceeding the

specification value.

Restore the power to the correct state.

2 Check the input voltage.

The voltage is within the specification

value.

Investigate investigation item 3 and

remedy.

The correct values are not set. Set the correct values.

3 Check all of the spindle parameters.

The correct values are set.

Investigate investigation item 4 and

remedy.

The signals are not input or the

sequence is incorrect.

The orientation command is input.

Correct the input signals.

Check the input signals.

• Are the READY, forward run and

reverse run signals input?

• In particular, the forward run and

reverse run signals must be input at

least one second after READY is

turned ON.

• Check whether the forward run and

reverse run signals are turned ON

simultaneously.

No particular problems found.

Investigate investigation item 5 and

remedy.

The speed command is not input

correctly.

Input the correct speed command.

5 Check the speed command.

The speed command is input correctly. Replace the unit.

[2] No fault is displayed, but the motor only rotates slowly, or a large noise is heard from the

motor.

Investigation item Investigation results Remedies

The wires are not connected correctly. Correctly connect.

Check the U, V and W wiring between the

spindle drive unit and motor.

The wires are connected correctly.

Investigate investigation item 2 and

remedy.

2 Check the input voltage.

One of the three phases is not within the

specification value.

No particular problems found.

Restore the power to the correct state.

Investigate investigation item 3 and

remedy.

The speed command is not input

correctly.

Check the NC and PLC sequence.

3 Check the speed command.
