3 Wiring and Connection3.1.4 Using the SERVOPACK with a DC Power Input3-143.1.4 Using the SERVOPACK with a DC Power Input(1) Parameter SettingWhen using a DC power supply, make sure to set the parameter Pn001.2 to 1 (DC power input supported)before inputting DC power.Observe the following precautions.(2) DC Power Supply Input Terminals for the Main and Control Circuits Three-phase, 200 V for SGDV-A( = R70, R90, 1R6, 2R8, 3R8, 5R5, 7R6, 120, 180, 200, 330) Three-phase, 200-V for SGDV-A( = 470, 550, 590, 780) Three-phase, 400 V for SGDV-D( = 1R9, 3R5, 5R4, 8R4, 120, 170, 210, 260, 280, 370)Parameter Meaning When Enabled ClassificationPn001 n.0 Enables use of AC power input. After restart Setupn.1 Enables use of DC power input.WARNING• Either AC or DC power can be input to the 200-V, 400-V SERVOPACKs. Always set Pn001.2 to 1 to spec-ify a DC power input before inputting DC power. Only AC power can be input to the 100-V SERVOPACKs.If DC power is input without changing the parameter setting, the SERVOPACK’s internal elements will burn andmay cause fire or damage to the equipment.• With a DC power input, time is required to discharge electricity after the main power supply is turned OFF.A high residual voltage may remain in the SERVOPACK after the power supply is turned OFF. Be carefulnot to get an electric shock.• Install fuses on the wires if DC power is used.• Servomotor returns a regenerated energy to the power supply. The SERVOPACK that can use a DCpower supply is not capable of processing the regenerated energy. Provide measures to process theregenerated energy on the power supply.• With a DC power input, connect an external inrush current limit circuit.Failure to observe this caution may result in damage to the equipment.Terminal Symbols Name SpecificationsB1/ Main circuit positive terminal 270 to 320 VDC2 Main circuit negative terminal 0 VDCL1C, L2C Control power input terminal 200 to 230 VACTerminal Symbols Name SpecificationsB1/ Main circuit positive terminal 270 to 320 VDCMain circuit negative terminal 0 VDCL1C, L2C Control power input terminal 200 to 230 VACTerminal Symbols Name SpecificationsB1/ Main circuit positive terminal 513 to 648 VDC2 Main circuit negative terminal 0 VDC24 V, 0 V Control power input terminal 24 VDC ±15%
