Otherwise this will be reason of fault.
If there is an abnormal voice or not voice of touching when relay acts, please
contact manufacturer directly.
Whether there is abnormal phenomenon of power indicator-light and LED.
8-2 Maintenance
◇
Using and storing the product in a proper and normal environment.
◇
Periodically clean the surface and panel of servo drive and motor, avoid adhesion of dust and
dirt.
◇
Do not disassemble or damage any mechanical part when performing maintenance.
◇
Clean off any dust and dirt with a vacuum cleaner. Place special emphasis on cleaning the
ventilation ports and PCBs. Always keep these areas clean, as accumulation of dust and dirt
can cause unforeseen failures
8-3 Lifespan of servo drive components
Smooth capacitor
◇
The characteristics of smooth capacitor would be deteriorated by ripple current affection. The
life of smooth capacitor varies according to ambient temperature and operating conditions. The
common guaranteed life of smooth capacitor is ten years when it is properly used in normal
air-conditioned environment.
Relay
◇
The contacts will wear and result in malfunction due to switching current. The life of relay
varies according to power supply capacity. Therefore, the common guaranteed life of relay is
cumulative100,000 times of power on and power off.
Cooling fan
◇
The cooling fan life is limited and should be changed periodically. The cooling fan will reach
the end of its life in 2~3 years when it is in continuous operation. However, it also must be
replaced if the cooling fan is vibrating or there are unusual noises.
