L1, L2
Control circuit
terminal
Used to connect single-phase AC control circuit power.
(Control circuit uses the same voltage as the main circuit.)
R, S, T
(for 220V models)
L1M, L2M
(for 110V models)
Main circuit
terminal
Used to connect single-phase or three-phase AC main
circuit power depending on connecting servo drive model.
For single-phase 220V models, connect R and S terminals
to power. For single-phase 110V models, connect L1M and
L2M terminals to power. For three-phase models, connect
all three R, S, and T terminals to power. To provide control
circuit power, two jumpers can be added from R and S to
L1 and L2.
