Terminal
Description
Control circuit The servo Control Circuit requires an independent 220V
terminal single-phase VAC supply.
The Main Circuit Terminal is used to supply the servo with
line power. If a single-phase supply, is used connect the R
Main circuit terminal 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.

Usually, the braking unit is not necessary. It is used to
absorb the large regenerative power that is generated when
the external load is much greater than the motor torque.
