3 Wiring and Connection3.8.1 Selecting a Regenerative Resistor Unit3-363.8 Selecting and Connecting a Regenerative Resistor UnitThe SERVOPACKs and converters do not contain a regenerative resistor. Select and connect a regenerativeresistor unit and set the regenerative resistor capacity in Pn600 as described in this section.For detailed specifications of the regenerative resistor units, refer to Large-CapacityΣ-V Series Catalog (No.:KAEP S800000 86).3.8.1 Selecting a Regenerative Resistor Unit(1) Using a Regenerative Resistor Unit Specified by YaskawaThe regenerative resistor units specified by Yaskawa are listed in the following table. You must acquire theregenerative resistor units separately.If you use a regenerative resistor unit specified by Yaskawa, use it only in one of the combinations that aregiven in the following table.(2) Using a Non-Specified Regenerative Resistor UnitIf you use non-specified regenerative resistor units, contact your Yaskawa representative or the sales depart-ment for more details.WARNING• Be sure to connect the regenerative resistor unit correctly. Do not short-circuit between B1 and B2.Doing so may result in fire or damage to the regenerative resistor unit, SERVOPACK, or converter or other devices.Main CircuitPower SupplyVoltageSERVO-PACKModelSGDV-ConverterModelSGDV-COAModel of ApplicableRegenerativeResistor UnitResis-tance(Ω)SpecificationsThree-phase200 V121H 2BAA JUSP-RA08-E 2.4 Four 0.6-Ω (600-W) resistors con-nected in series161H3GAAJUSP-RA09-E 1.8Two sets of four 0.9-Ω (600-W)resistors connected in series areconnected in parallel.201H JUSP-RA11-E 1.6 Eight 0.2-Ω (600-W) resistors con-nected in seriesThree-phase400 V750J 3ZDA JUSP-RA13-E 6.7Three sets of two 10-Ω (600-W)resistors connected in series areconnected in parallel.101J5EDAJUSP-RA14-E 5Four sets of two 10-Ω (600-W)resistors connected in series areconnected in parallel.131J JUSP-RA16-E 3.8Four sets of three 5-Ω (600-W)resistors connected in series areconnected in parallel.If you use a non-specified regenerative resistor unit, we recommend that you use aregenerative resistor unit with a thermal switch for safety.
