Please use and store the product in a proper site.
Periodically clean the surface of the servo drive and servo motor so as to avoid the
dust and dirt.
Do not disassemble any mechanical part when in maintenance.
Periodically clean the ventilation ports of the servo drive and do not use the product in
a high-temperature site for a long time so as to avoid the malfunction.
Lifespan of Machinery Parts
Smoothing Capacitor
The smoothing capacitor deteriorates if affected by the ripple current, and its lifespan
is determined by the surrounding temperature and operating conditions. If it is used in
an air-conditioned site, its lifespan can be up to 10 years.
Relay
The contacts will wear due to switching the power on and off, which will lead to poor
contact. The lifespan of the relay varies according to the power supply capacity. Thus,
the accumulative times of switching the power supply on and off is about 100,000 times.
Cooling Fan
In continuous operation, the lifespan of the cooling fan is 2 to 3 years. However,
if there is any unusual noise or vibration during inspection, please replace the fan.
B-2
If the peripheral devices are interfered by the electronic instruments,
please reduce electromagnetic interference with devices.
Please make sure the external voltage level of the servo drive is
correct.
The encoder cable should avoid excessive stress. When the motor
is running, please be ensured the cable is not frayed or over
extended.
Please contact with Delta if there is any vibration of the servo motor
or unusual noise during the operation.
Make sure the setting of the parameters is correct. Different
machinery has different characteristic, please adjust the parameter
according to the characteristic of each machinery.
Please reset the parameter when the servo drive is in the status of
SERVO OFF, or it may cause malfunction.
When the relay is operating, make sure it can work properly.
Check if the power indicator and LED display works normally.
