● Servo drives in size E (rated power: 2.0 kW to 7.5 kW): SV670NS018I,
SV670NS022I, SV670NS027I, SV670NT017I, SV670NT021I, and SV670NT026I

Name
Description
L1C, L2C (control
circuit power input
terminals)
See the nameplate for the rated voltage class.
R, S, and T (main
circuit power input
terminals)
[1]
Power input terminals of the servo drive. See the nameplate for
the rated voltage class.
P⊕, D, and C
(terminals for
connecting an
external braking
resistor)
[2]
Remove the jumper bar between terminals P⊕ and C before
connecting an external regenerative resistor between terminals
P⊕ and D.
N2, N1 (terminals for
connecting external
reactor)
Terminals N1 and N2 are jumpered by default. To suppress
harmonics in the power supply, remove the jumper between
terminals N1 and N2 first and connect an external DC reactor
between terminals N1 and N2.
U, V, W (terminals for
connecting the servo
motor)
Connected to U, V, and W phases of the servo motor.
Note
● [1]: The power input terminals of the 220V servo drive’s main circuit are L1, L2, and
L3; and the power input terminals of the 380V servo drive’s main circuit are R, S,
and T.
● [2] The built‑in braking resistor or jumper bar is not available in models S1R6 and
S2R8. If an external regenerative resistor is needed for these models, connect it
between terminals P⊕ and C.
