3.6 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
Σ
-V series Product Catalog
(KAEP S800000 42).
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/ and B2 terminals. After connecting a resistor, select
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/ and B2 terminals or between the B1 and B2 terminals. After connecting a resistor,
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.
WARNING
• Be sure to connect the regenerative resistor correctly.
Failure to observe this warning may result in fire or damage to the product.
