12.8 Regenerative Resistor
12.8.6 Selecting External Regenerative Resistor
12-38
 SERVOPACK Model: SGD7S-3R8A, -5R5A, -7R6A, -120A, -180A,
-200A,-330A, -470A, -550A, -590A, or
-780A
SGD7W-1R6A, -2R8A, -5R5A, or -7R6A
SGD7C-1R6A, -2R8A, -5R5A, or -7R6A
The above SERVOPACKs require regenerative resistors. Regenerative resistors are built into all
of the SERVOPACKs in advance except for the SGD7S-470A, -550A, -590A, and -780A. If you
use the SGD7S-470A, -550A, -590A, or -780A, always provide an external regenerative resis-
tor. Refer to the following section for details.
12.8.3 Selection Table on page 12-33
The allowable frequencies for regenerative operation of the Servomotor without a load in accel-
eration/deceleration operation during an operation cycle from 0 (min
-1
) to the maximum motor
speed and back to 0, are listed below. For the SGD7S-470A, -550A, -590A, and -780A, the
allowable frequencies are given for when a Regenerative Resistor Unit is connected. Refer to
the following section for details on Regenerative Resistor Units.
Regenerative Resistor Units on page 12-36
Convert the data into the values for the actual motor speed and load moment of inertia to
determine whether an External Regenerative Resistor is required.
