1. Checking and Handling
1.1 Handling (Connection of main circuit and motor)
Thank you for purchasing HIGEN AC Servo Driver. Incorrect handling of the driver may lead to
unsatisfactory operation or, in some cases, to the rapid reduction of its life, or damage to the servo.
Handle and operate the driver according to the instructions given in this manual.
distance. (Caution) Use higher than class-3 earth
* Power Supply : Use power supply within specification
(3-phase AC200~230V)
(Caution!) If the power voltage is AC 440V,use a
transformer to change AC 440V to AC 220V
* Install magnetic contactors
Do not use magnetic contactor to start or stop the servo
as it may reduce its life.
* No Fuse Circuit Breaker or Auto Breaker : Large level
of current flows when power is applied to the servo
For selection of breakers, refer to Table 3.1, chapter3.3
* Installation place : The operating life of the servo is
affected by ambient temperature.
Maintain ambient temperature at a level below 50℃
* Wiring : Improper wiring may damage to the servo. The control
signal line must be sufficiently away from the main
circuit wiring so that the line is not affected by
noises.
* Connection with output terminals : Do not connector condensers
,radios or noise filters during operation as it may
cause damage to the equipment.
* Grounding : To prevent electric shock and effectively control
noise,ground the motor and driver at the shortest
* Motor system : Do not strike the motor shaft and detecter with
a hammer.
(Caution) Impact may cause damage th the encoder inside the motor
* Noise Filter : Use noise filters to eliminate external
noise that comes with the commercial power supply
For selection of noise filters, refer to Table3.1, Chapter3.3
