Chapter III Wiring
3.1 Notices
● The servo driver is a high voltage e heavy current product. Improper connection may cause
damage to personnel and equipment.
● PE terminal must be connected to a ground wire and make sure that the ground wire is reliably
grounded.
●AC 220V power supply is suitable for this product. Do not connect an AC380V one to the servo
driver.
● The U, V and W of the product should be connected with the motor. They are outputs. Do not
connect them with input power supply.
● Do not connect the three-phase outputs U, V and W of the product in an incorrect sequence;
because incorrect connection may lead to motor racing, damage to equipment, and overcurrent
burnout to the product.
● Tighten all terminals. The materials of all matching wires should be strictly selected according
to power.
●Power distribution and touching of the terminals are not allowed when the driver is electrified.
● Do not touch the terminals within five (5) minutes after power down.
● It is not allowed to touch the motor and cables when the motor is in operation in order to avoid
accidental injuries such as scalding and wrench, etc.
3.2 Wiring Requirements
● A three-phase isolation transformer is preferred for power supply.
● The required diameters of R, S, T and U, V, W, PE wires should be equal to and more than
1.5mm2.
● All power terminals should be cold-pressed ones, firm and reliable.
●CN1 and CN2 are high-density signal plugs that need cables with a shielding layer.
● The wires for connecting PE terminals should be yellow-green ones with a diameter equal to
and more than 2.5mm2.
3.3 Wiring Methods
●A three-phase isolation transformer is preferred for power supply.
