B-2 Revision February, 2017
running the servo drive
(has already applied to
the power)
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.
Maintenance
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.
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 up to 10 years.
Relay
The contact of switching power supply will wear and leads 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, place a new one is a must.
