3.1.4 Using the SERVOPACK with a DC Power Input
(1) Parameter Setting
When 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 SGDV-550A
 Three-phase, 400 V for SGDV-D 
( = 1R9, 3
R5, 5R4, 8R4, 120, 170, 260)
Parameter Meaning When Enabled Classification
Pn001
n.0 Enables use of AC power input.
After restart Setup
n.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 powe
r 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 and
may cause fire or damage to the equipment.
• With a DC power input, time is required to discharge e
lectricity 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 careful
not 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 DC
power supply is not capable of processing the regenerated energy. Provide measures to process the
regenerated 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.
