Description
The servo Control Circuit requires an independent 220V
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 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
Internal resistor
External 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.
