Bus voltage indicator
Used to indicate the bus capacitor with charges. When the indicator turns on,
charges possibly still exist in the internal capacitor of the servo unit, even if the power
supply of the main circuit is OFF. Therefore, do not touch the power terminals to
avoid electrical shock.

for the drive unit
Main circuit single-phase and three-phase 220 V power input.
Terminals L1 and L2 are for single-phase power input, and terminals L1, L2 and L3 are for
three-phase power input.
Control circuit 220 V AC power input.
P, N ： They are used for common DC bus connection when multiple servo drives are under
parallel control.
Two grounding terminals of the servo drive are respectively connected to those of the power
supply and the servo motor.

External bleeder resistor is connectedbetween P and C when the servo systemis under
feedbackBraking mode. Externalis under feedbackresistor needs to be purchased additionally.

U, V, W: Connect the phases U, V and W of servo motor
24 V brake power input (you must use this port to input 24 V
power in order to use the brake power)
Note The motor with brake must be supplied with 24 V power via the CN7 terminal on the servo
drive. The power must be output to the wiring terminal of the brake via BR+ and BR-.
