Danger!
◆This equipment is with hazardous voltage. Operations against
warnings or this Manual may incur life risk and personal injury.
Therefore only professionals familiar with safety precautions are
allowed to operate the equipment after completion of its
installation.
◆Power off during wiring and inspection. Do not touch the circuit
board or any part before the indication light on the printed circuit
board goes out or within 5 minutes since the keyboard display
goes out. Perform operations within the machine only when
completion of discharging has been confirmed by the special
instrument to exclude hazard of electric shock.
◆It is forbidden to connect the AC power supply to output terminal
U, V, W of the servo drive. Please perform earth connection of
the grounding terminals of the servo drive in a correct and
reliable manner in accordance with electric safety regulations of
IEC or other similar standards.
◆It is forbidden to connect the AC power supply to servo motor U,
V, W, to avoid possible equipment damage or personal injury.
Warning!
◆Unauthorized change to wiring within the machine or utilization
of auxiliaries purchased from illegal manufacturers may incur
fire disaster, electric shock or personal injury.
◆As the static electricity from human body will cause serious
damage to static electricity susceptible device, please do not
touch the printed circuit board and IGBT module with your
hands when anti-static precautions are not taken, or there may be
a fault.
◆Do not mount the servo drive and servo motor on
incombustibles. If mounted on or around combustibles, the servo
drive or servo motor may be exposed to fire disasters.
Caution!
◆The servo drive shall be used along with compatible servo motor
with supporting performance.
◆Users who intend to employ their own servo motor should
contact our technicians to make sure that such motor will run
normally.

Chapter I Purchase Inspection
1.1 Unpacking Inspection
The servo drive system has been tested and checked strictly before delivery. However,
please check the purchased product of the following items to avoid unnecessary
mistakes during purchasing and transport.
Whether the purchased product is the expected one: for this, the product model on
the nameplates of the motor and drive should be checked with reference to model
description outlined in the next section.
Whether the motor shaft rotates in a smooth manner: for this, manually rotate the
motor shaft to see whether it is able to run smoothly. If yes, it is deemed normal.
However, the inspection manner of manual rotation is not applicable to the motor
with an electromagnetic holding brake.
Damage inspection: for this, conduct visual inspection on the product for damage
or scratching.
Unreliable screws: check whether any screw is not fixed in a reliable manner or is
loosening.
In any of above mentioned cases, do not hesitate to contact the dealer for problem
solving.
