Power Device
Check whether there
are dust
Blow off with dry compressed air
(pressure 4~6kg/cm
2
)
Electrolytic
Capacitor
Check whether there
are discoloration,
peculiar smell,
bubble, leakage, etc.
Replace the electrolytic capacitor
Braking Resistor
Check whether there
is good ground
insulation.
Keep the braking resistor in a dry and
insulated place
During the inspection, the device should not be dismantled or shook arbitrarily, and the
connector should not be pulled up arbitrarily as well. Otherwise may cause abnormal
operation of servo drive or display malfunction. Moreover, it may cause device failure,
damage of main switching devices IGBT module or other devices.
8.1.3 Regular Replacement of Devices
Periodic Maintenance based on the service life of internal electronic components of
servo drive is necessary for the long-term reliability service. The service life of
electronic components may change according to the different working environments
and working conditions. In general continuous using, they could be replaced according
to the following table, and depended on the specific situations, such as the working
environments, load conditions and current situation of servo drive.
The maintenance period of servo drive in table 8-4 is for reference only.

8.2 Storage and Protection
The servo drive shall not be used immediately after the purchase, and the followings
shall be noticed for the temporary or long-term storage:
 The servo drive belongs in the stated scope of temperature and humidity. Ensure
that there are no humidity, dust, metallic dust but with good ventilation.
