9.2Maintenance

„Use and store the product in a proper and normal environment.

„Periodically clean the surface and panel of servo drive and motor.

„Make sure the conductors or insulators are corroded and/or damaged.

„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.

9.3Life of Replacement 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 cumulative 100,000 times of power on and power off.
