Chapter 8 Maintenance and Inspections

Modern AC motor drives are based on solid-state electronics technology. Preventive maintenance is required to keep the AC motor drive in its optimal condition, and to ensure a long life. It is recommended to have a qualified technician perform a check-up of the AC motor drive regularly.

Daily Inspection:

Basic check-up items to detect if there were any abnormalities during operation are:

1.Whether the motors are operating as expected.

2.Whether the installation environment is abnormal.

3.Whether the cooling system is operating as expected.

4.Whether any irregular vibration or sound occurred during operation.

5.Whether the motors are overheating during operation.

6.Always check the input voltage of the AC drive with a Voltmeter.

Periodic Inspection:

Before the check-up, always turn off the AC input power and remove the cover. Wait at least 10 minutes after all display lamps have gone out, and then confirm that the capacitors have fully discharged by measuring the voltage between ~ . It should be less than 25VDC.

DANGER!

1.Disconnect AC power before processing!

2.Only qualified personnel shall install, wire and maintain AC motor drives. Please take off any metal objects, such as watches and rings, before operation. And only insulated tools are allowed.

3.Never reassemble internal components or wiring.

4.Prevent electric shocks.
