Specification
• SGD7S-R70A, -R90A, -1R6A, and
-2R8A
If the regenerative capacity is insuffi-
cient, connect an External Regenera-
tive Resistor between B1/
Obtain an External Regenerative Resis-
tor separately.
• SGD7S-3R8A, -5R5A, -7R6A, -120A, -
180A, -200A, and -330A;
SGD7W-1R6A, -2R8A, -5R5A, and
-7R6A
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.
• SGD7S-470A, -550A, -590A, and
-780A
Connect a Regenerative Resistor Unit
between B1/
and B2. Obtain a
Regenerative Resistor Unit separately.
These models do not have a B3 termi-
nal.
These terminals are to connect a DC reac-
tor for power supply harmonic suppres-
sion and power factor improvement.
None. (Do not connect anything to this
terminal.)
Note: The SGD7S-330A to -780A
SERVOPACKs do not have a
terminal.
These are the -7S connection terminals
for the Servomotor Main Circuit Cable
(power line).
These are the -7W connection terminals
for the Servomotor Main Circuit Cable
(power line).
