Using the SERVOPACK with a DC Power Input
(1) Parameter Settings
When using the SERVOPACK with a DC power input, set parameter Pn001.2 to 1.
Observe the following precautions when using a 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 and
may cause fire or equipment damage.
• 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 careful
not to get an electric shock.
• Install fuses on the wires if DC power is used.
• Linear 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 product.
