Chapter 3 Connections and wiring
Servo drive power use three-phase AC 220 V, general, that was gained from three-phase AC 380 V
through the transformer. S
pecially, l
ess than 1 KW motor could use single-phase 220V
(Single-phase power is connected to any 2 terminals of R, S, T).

1. Check if the wiring of control circuit power (L1, L2) and main circuit power (R, S, T) are
correct.
2. Ensure the voltage class of supply power consistent with the rated voltage of servo drive, if
the voltage class of supply power out of range will damage the product.
3. Check the U, V, W cable is properly connected.
4. Ensure that the drive and motor are correctly connected to a ground.
5. Braking resistance is internal connected to RB and RB1,usually does not need to link
external braking resistance, if internal braking resistance can't meet the demand, parallel in
the RB, RB1 terminals with corresponding resistance .
6. If a fault or emergency stop occurs, using ALARM digital output can control
electromagnetic contactor and cut off the power of the servo drive.
7. Ensure that all necessary screws are tight and secure.

The servo Control circuit requires an independent 220V
single-phase VAC supply.

Main circuit input
terminals
The Main Circuit Terminal is used to supply the servo
with line power. If a single-phase supply, is used
connect the R and S terminals to power. If 3-phase,
connect all three R, S, & T terminals. To provide
Control Circuit power two jumpers can be added from R
and S to L1 and L2.

Wiring connection should pay close attention to follows:
1) As a residual hazardous voltage may remain inside the drive, please do not immediately touch any
of the "power" terminals (R, S, T, U, V, & W) and the cables connected to them after the power has
been turned off and the charge LED is light.
