Control circuit and main R, S and T can be connected to a signal-phase or three-phase 220V

circuit power supply 50HZ power supply. The control power supply for the driver and

manner.

Note that It should not be connected to U, V and W.

Power supply ground wire Connected to the equipment housing and the power supply earth

of the workshop.

External connection to Normally not used, because the driver has a built-in resistor.

braking resistors

Externally connected braking resistors are used in case of a load

with large inertia.

Output to the servo motor U, V and W on the servo terminals must correspond to the ones on

the servo motor without misplacement. In case of incorrect

connection, the motor will pulsate, the servo will alarm, and the

servo and motor could be damaged.

Note that it should not connected with R, S and T.

Motor ground wire

Connected to the PE for the housing of the servo motor.
