Description
Main circuit input
terminals
L1, L2 F
Single-phase 100 to 115 V,
+10% to -15% (50/60 Hz)
L1, L2, L3
A
Three-phase 200 to 230 V,
+10% to -15% (50/60 Hz)

Three-phase 380 to 480 V,
+10% to -15% (50/60 Hz)
Control power input
terminals
L1C, L2C
F
Single-phase 100 to 115 V,
+10% to -15% (50/60 Hz)
A
Single-phase 200 to 230 V,
+10% to -15% (50/60 Hz)
24V, 0V D

±15%
External regenerative
resistor terminals
B1/ , B2,
or
B1, B2
R70F, R90F, 2R1F, 2R8F,
R70A, R90A, 1R6A, 2R8A
If the regenerative capacity is insuffi-
cient, connect an external regenerative
resistor (option) between B1/ and B2.
3R8A, 5R5A, 7R6A, 120A,
180A, 200A, 330A, 1R9D,
3R5D, 5R4D, 8R4D, 120D,
170D
If the internal regenerative resistor is
insufficient, remove the wire between B2
and B3 and connect an external regenera-
tive resistor (option) between B1/ and
B2, or B1 and B2.
470A, 550A, 590A, 780A,
210D, 260D, 280D, 370D
Connect a regenerative resistor unit
(option) between B1/ and B2, or B1
and B2.
DC reactor
connection terminal
for power supply
harmonic
suppression
1, 2
A
D
Normally short 1 and 2.
If a countermeasure against power supply
harmonic waves is needed, connect a DC
reactor between 1 and 2.
