, B2, and
B3
Regenerative Resistor
terminals
• SGD7S-R70A, -R90A, -1R6A, and
-2R8A
If the regenerative capacity is insuffi-
cient, connect an External Regenera-
tive Resistor between B1/
and B2.
Obtain an External Regenerative Resis-
tor separately.
• SGD7S-5R5A, -120A
008,
SGD7W-1R6A, SGD7W-2R8A, and
SGD7W-5R5A
If the regenerative capacity is insuffi-
cient, remove the lead or short bar
between B2 and B3 and connect an
External Regenerative Resistor between
B1/
and B2. Obtain an External
Regenerative Resistor separately.

DC Reactor terminals
for power supply har-
monic suppression
These terminals are to connect a DC reac-
tor for power supply harmonic suppres-
sion and power factor improvement.
L3 and
None. (Do not connect anything to this
terminal.)
U, V, and W
Servomotor terminals
These are the
-7S connection terminals
for the Servomotor Main Circuit Cable
(power line).
UA, VA, and
WA
Servomotor terminals
for axis A
These are the
-7W connection terminals
for the Servomotor Main Circuit Cable
(power line).
UB, VB, and
WB
Servomotor terminals
for axis B
D1 and D2
Dynamic Brake Resis-
tor terminals
These terminals are provided only on
SERVOPACKs that support the Dynamic
Brake Option. These terminals are used to
connect an External Dynamic Brake
Resistor for a
-7S SERVOPACK. Obtain
an External Dynamic Brake Resistor sep-
arately.
Note: The SGD7S-R70A to -2R8A
SERVOPACKs do not have D1 and
D2 terminals.
