Control circuit
terminal
The servo Control Circuit requires an independent 220V
single-phase VAC supply.
R, S, T
Main circuit terminal
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.
Used to connect servo motor

Braking unit is suitable for 2kW and above models.
When using braking unit, ensure to connect (+) terminal of
the braking unit to P , main circuit (+) terminal of the servo
drive, and connect (-) terminal of the braking unit to ,
main circuit (-) terminal of the servo drive.
The braking unit is an optional part.
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.
