8. INSPECTION
WARNING
Before starting maintenance and/or inspection, make sure that the charge lamp is off more than 15 minutes after power-off. Then, confirm that the voltage is safe in the tester or the like. Otherwise, you may get an electric shock.
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
Smoothing capacitor
Servo amplifier
Relay
Cooling fan
Absolute position battery
Life guideline
10 years
Number of power-on and number of forced stop times:100,000times.
10,000 to 30,000hours (2 to 3 years)
Refer to Section 13.2
(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.
