Description Notes
L1, L2 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.
