3 Wiring and Connection3.6.1 Connecting Regenerative Resistors3-403.6 Connecting Regenerative ResistorsThis section describes how to connect the regenerative resistor and set the regenerative resistor capacity. Asfor precautions on selecting a regenerative resistor and its specifications, refer toΣ-V series Product Catalog(KAEP S800000 42).3.6.1 Connecting Regenerative ResistorsThe following instructions show how to connect the regenerative resistors and SERVOPACKs.(1) SERVOPACKs: Model SGDV-R70F, R90F, 2R1F, 2R8F, R70A, R90A, 1R6A,2R8AConnect an external regenerative resistor between B1/ and B2 terminals. After connecting a resistor, selectthe capacity. For more information on how to set the capacity of regenerative resistors, refer to 3.6.2 SettingRegenerative Resistor Capacity.(2) SERVOPACKs: Model SGDV-3R8A, 5R5A, 7R6A, 120A, 180A, 200A, 330A,1R9D, 3R5D, 5R4D, 8R4D, 120D, 170DDisconnect the wiring between the SERVOPACK’s B2 and B3 terminals and connect an external regenerativeresistor 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 3.6.2Setting 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.Enlarged ViewEnlarged View
