connector
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.
Used to connect servo motor

Ensure the circuit is closed between P
Internal resistor and D, and the circuit is open between
P and C.
Connect regenerative resistor to P and
External resistor C, and ensure an open circuit between
P and D.
Only 750W and above servo drives are provided with built-
in regenerative resistors. Ensure to leave the circuit closed
between P and D when using a built-in (internal)
regenerative resistor.
Used to connect grounding wire of power supply and servo
motor.
Used to connect external controllers. Please refer to section
3.3 for details.
Used to connect encoder of servo motor. Please refer to
section 3.4 for details.
