3.3.4 When Using the SERVOPACK with a DC Power Input
(1) Parameter Setting
When using the SERVOPACK with a DC power input, make sure to set the
parameter Pn001.2 to 1 before inputting DC power .
Observe the following warnings.

WARNING
• Either AC or DC power can be input to the 200 V and 400 V SERVOPACKs.
Always set Pn001.2 to 1 to specify 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 SERVO-
PACK 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 SER-
VOPACK that can use a DC power supply is not capable of processing the regen-
erated 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.
