10.INSPECTION

10.INSPECTION

Before starting maintenance and/or inspection, make sure that the charge lamp is off more than 10 minutes after power-off. Then, confirm that the voltage is safe in

the tester or the like. Otherwise, you may get an electric shock.

WARNING Any person who is involved in inspection should be fully competent to do the work. Otherwise, you may get an electric shock. For repair and parts replacement, contact your safes representative.

POINT

Do not test the servo amplifier with a megger (measure insulation resistance), or it may become faulty.

Do not disassemble and/or repair the equipment on customer side.

(1)Inspection

It is recommended to make the following checks periodically:

(a)Check for loose terminal block screws. Retighten any loose screws.

(b)Check the cables and the like for scratches and cracks. Perform periodic inspection according to operating conditions.

(2)Life

The following parts must be changed periodically as listed below. If any part is found faulty, it must be changed immediately even when it has not yet reached the end of its life, which depends on the operating method and environmental conditions. For parts replacement, please contact your sales representative.

 

Part name

Life guideline

 

Smoothing capacitor

10 years

 

Relay

Number of power-on and number of forced

Servo amplifier

stop times : 100,000 times

 

 

Cooling fan

10,000 to 30,000hours (2 to 3 years)

 

Absolute position battery

Refer to Section 4.5

(a)Smoothing capacitor

Affected by ripple currents, etc. and deteriorates in characteristic. The life of the capacitor greatly depends on ambient temperature and operating conditions. The capacitor will reach the end of its life in 10 years of continuous operation in normal air-conditioned environment.

(b)Relays

Their contacts will wear due to switching currents and contact faults occur. Relays reach the end of their life when the cumulative number of power-on and forced stop times is 100,000, which depends on the power supply capacity.

(c)Servo amplifier cooling fan

The cooling fan bearings reach the end of their life in 10,000 to 30,000 hours. Normally, therefore, the fan must be changed in a few years of continuous operation as a guideline.

It must also be changed if unusual noise or vibration is found during inspection.
