18. Troubleshooting

Check corresponding item given in this chapter to take corrective actions when the unit seems to be

faulty. If the fault persists, please contact your sales agent (M/C maker) or us. When making an inquiry,

let us know the product type and manufacturing number marked on the nameplate of the NC rotary table

body.

Nameplate

Symptom

①：

Table does not rotate

Possible causes

Corrective actions

No cable connection between NC rotary
table and control unit

Check the cable for connection, and connect
it

Broken cable between NC rotary table and
control unit

Check the cable for continuity, and replace it

Faulty clamp device

See

“Symptom

⑤

”

Decentered workpiece, overloaded fixture,
and friction torque of steady rest and rotary
joint make the load torque larger than the
motor torque

Compare the specification of NC rotary table
with the work condition to make
improvement

Use of unit out of specified temperature
range

Adjust ambient temperature within specified
temperature range

Symptom

②：

Table does not rotate but generates a noise

Possible causes

Corrective actions

Motor makes a howling sound to try to rotate

→

Seizure of gears due to lack or
deterioration of lubricating oil

Stop the use of NC rotary table immediately.
Please contact the sales agent.

Gears generate a noise

→

Faulty rotation due to damaged gears

Stop the use of NC rotary table immediately.
Please contact the sales agent.

Unit generates a noise at startup and stops
soon

→

Faulty rotation because foreign
substances mix in the oil bath

Supply lubricating oil until foreign
substances come out of the drain port.
