Connecting Regenerative Resistors

This section describes how to connect the regenerative resistor and set the regenerative resistor capacity. As
for precautions on selecting a regenerative resistor and its specifications, refer to
(KAEP S800000 42).
• Be sure to connect the regenerative resistor correctly.
Failure to observe this warning may result in fire or damage to the product.
3.6.1 Connecting Regenerative Resistors
The following instructions show how to connect the regenerative resistors and SERVOPACKs.
(1) SERVOPACKs: Model SGDV-R70F, R90F, 2R1F, 2R8F, R70A, R90A, 1R6A,
2R8A
Connect an external regenerative resistor between B1/
the capacity. For more information on how to set the capacity of regenerative resistors, refer to 3.6.2 Setting
Regenerative Resistor Capacity.
(2) SERVOPACKs: Model SGDV-3R8A, 5R5A, 7R6A, 120A, 180A, 200A, 330A,
1R9D, 3R5D, 5R4D, 8R4D, 120D, 170D
Disconnect the wiring between the SERVOPACK's B2 and B3 terminals and connect an external regenerative
resistor between the B1/
select the capacity. For more information on how to set the capacity of regenerative resistors, refer to 3.6.2
Setting Regenerative Resistor Capacity.
Note: Be sure to take out the lead wire between the B2 and B3 terminals.
