2. Quality of the batteries degrades by the storage condition. The battery life is 5 years from the production date
regardless of the connection status.
(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 (40 °C (104 °F) surrounding air temperature or
less).
(b) Relays
Contact faults will occur due to contact wear arisen from switching currents. Relays reach the end of their
lives when the power is turned on and emergency stop occurs 100,000 times in total, or when the STO has
been turned on and off 1,000,000 times while the servo motor is stopped under servo-off state. However,
the lives of relays may depend on the power supply capacity.
(c) Servo amplifier cooling fan
The cooling fan bearings reach the end of their life in 50,000 hours to 70,000 hours. Normally, therefore,
the cooling fan must be changed in seven or eight years of continuous operation as a guideline. It must also
be changed if unusual noise or vibration is found during inspection.
The life indicates under the yearly average ambient temperature of 40 °C (104 °F), free from corrosive gas,
flammable gas, oil mist, dust and dirt.
