CM3 – Maintenance and Inspection

Daily inspection

Daily

• Are there dust or foreign objects around the motor?

• Is there any abnormal vibration, noise or smell?

• Are the cables not damaged?

• Is there any loose connection or misalignment with other devices?

• Is the main circuit voltage normal?

Periodical inspection

Annually

• Is there any loose point at tightened points?

• Are terminals intact and not damaged?

There is no response in the software window or cannot operate a motor

Is the cabling between devices connected properly?

Please see the Wiring and Connection page and make sure all cables are connected properly. Confirm the state of the contact of the connector pins and the state of the harnesses. (Has a disconnection occurred?)

There is no response in the software window or cannot operate a motor

Are the communication settings set correctly when using communication software?

Once the CM3 baud rate is changed, the baud rate of the communication software must be changed as well. Read the Communication Functions page and create a new communication connection from the beginning.

There is no response in the software window or cannot operate a motor

Is the set value corresponding to the rewritten baud rate?

Please set the baud rate of the communication software to the same value as CM3.

There is no response in the software window or cannot operate a motor

Are there multiple communication software running?

If there is other software using COM ports, it may cause interference. Please close the software.

Noise and vibrations

Are the machine and the motor resonating?

Adjust the gain or speed of CM3.

Noise and vibrations

Damage to bearing?

Check the noise and vibrations with no load applied to the motor. If there is noise and vibrations, replacement or repair is required.

Overheat

Is the operating temperature within specification?

Do not use outside the specification.

Overheat

Check the mounting part on the machine.

Make sure there are no loose or slippery places in the machine.

Overheat

Is the load inertia within the allowable range?

Make sure that it is within the specification.

Overheat

Is the bearing not damaged?

Turn the power off and rotate the shaft. If there is a noise, then replacement or repair is required.

Does not rotate

Is the power ON?

Turn the power ON.

Does not rotate

Check cable connection

Connect the cables properly. Confirm the state of the contact of the connector pins and the state of the harnesses.

Does not rotate

Is the load within the allowable range?

Use it within the allowable load.

Does not rotate

Is the CM3 servo off?

Servo on the CM3.

Does not rotate

Is the motor in an alarm state?

Remove the cause of the alarm and reset the alarm.

Does not rotate

Has the STO been activated?

When STO is activated, the CM3 power circuit is cut off. Apply the voltage to the STO input.

Inaccurate origin

Is the origin search speed too high?

Decrease the origin search speed at the point close to origin.
