3 Wiring and Connection3.7.1 Connecting Regenerative Resistors3-303.7 Connecting Regenerative ResistorsIf the built-in regenerative resistor is insufficient, connect an external regenerative resistor by one of the fol-lowing methods and set the regenerative resistor capacity (Pn600). As for precautions on selecting a regenera-tive resistor and its specifications, refer toΣ-V Series Product Catalog (No.: KAEP S800000 42).3.7.1 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 the B1/ and B2 terminals on the SERVOPACK. Afterconnecting a resistor, select the capacity. For more information on how to set the capacity of regenerativeresistors, refer to 3.7.2 Setting Regenerative 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. After connecting the resistor, select the capacity. For more infor-mation on how to set the capacity of regenerative resistors, refer to 3.7.2 Setting Regenerative Resistor Capac-ity.Note: Be sure to take out the lead wire between the B2 and B3 terminals.WARNING• Be sure to connect the regenerative resistor correctly. Do not short-circuit between B1/ and B2.Doing so may result in fire or damage to the regenerative resistor or SERVOPACK.Enlarged ViewEnlarged View
