The lifetime of machinery parts
DC Bus Capacitor

DC Bus Capacitor will be deteriorated by the affection of ripple current. Its lifetime is
determined by the surrounding temperature and operating conditions. If it is operating in an
air-conditioned site, its lifetime can be up to 10 years.
Relay

The contact of switching power supply will wear and lead to poor contact. The lifetime of relay
is influenced by the power supply capacity; thus, the accumulative time of switching power
supply is about 100,000 times.
Cooling Fan

In continuous operation, the lifetime of the cooling fan is 2 to 3 years. However, if there is any
unusual noise or vibration during inspection, replacing a new one is a must.
B-2
Please contact 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 characteristics, 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, contact Delta if there is no contact noise or
there is other abnormal noise.
Check if the power indicator and LED display work normally.
