Inspection during
operation
(Control power is
applied)）
z Ensure that the cables are not damaged, stressed excessively or loaded
heavily. When the motor is running, pay close attention on the connection of the
cables and notice that if they are damaged, frayed or over extended.
z Check for abnormal vibrations and sounds during operation. If the servo motor
is vibrating or there are unusual noises while the motor is running, please
contact the dealer or manufacturer for assistance.
z Ensure that all user-defined parameters are set correctly. Since the
characteristics of various machinery are different, in order to avoid accident or
cause damage, do not adjust the parameter abnormally and ensure the
parameter setting is not an excessive value.
z Ensure to reset some parameters when the servo drive is off (Please refer to
Chapter 7). Otherwise, it may result in malfunction.
z If there is no contact sound or there be any unusual noises when the relay of
the servo drive is operating, please contact your distributor for assistance or
contact with Delta.
z Check for abnormal conditions of the power indicators and LED display. If there
is any abnormal condition of the power indicators and LED display, please
contact your distributor for assistance or contact with Delta.
9.2 Maintenance
„ 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.
9.3 Life 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.
