Wiring the Power Supply to the SERVOPACK

4.3.1

Terminal Symbols and Terminal Names

Use the main circuit connector on the SERVOPACK to wire the main circuit power supply and
control circuit power supply to the SERVOPACK.
The SERVOPACKs have the following four types of main circuit power supply input specifica-
tions.
• Three-Phase, 200-VAC Power Supply Input

4.3.5 Wiring Regenerative Resistors on page 4-23
 For SGD7S-R70A, -R90A, -1R6A, and -2R8A
If the regenerative capacity is insufficient, connect an Exter-
nal Regenerative Resistor between B1/
The External Regenerative Resistor is not included. Obtain it
separately.
 For SGD7S-3R8A,- 5R5A, -7R6A, -120A, -180A, -200A,
and -330A
If the internal regenerative resistor is insufficient, remove the
lead or short bar between B2 and B3 and connect an Exter-
nal Regenerative Resistor between B1/
The External Regenerative Resistor is not included. Obtain it
separately.
 For SGD7S-470A, -550A, -590A, and -780A
Connect a Regenerative Resistor Unit between B1/
B2. Obtain a Regenerative Resistor Unit separately. These
models do not have a B3 terminal.
