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. 

 

„

 

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. 

 

„

 

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. 

„

 

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.
