(4) DC Power Supply Input for SERVOPACK
When using a DC power supply for the SERVOPACK SGDS-A, use the terminals listed in the following
table and make sure that the parameter Pn001.2 is set to “1.” Also, observe the precautions given in IMPOR-
TANT.
1. The servomotor returns the 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.
2. With a SERVOPACK that is using DC power, a certain amount of time is required to discharge all
remaining electricity after the main power supply is turned OFF. Note that high-voltage electricity
remains in the SERVOPACK after the power supply is turned ON.

(b) Parameter Setting
• Do not use a DC power supply for the 100V SERVOPACK SGDS-F.
A DC power will destroy the SERVOPACK and may cause a fatal accident or fire. Do not change the factory setting
for Pn001 = n.0 (DC power supply input not supported).
• The AC and DC power can be used with the 200V SERVOPACK SGDS-A.
Before using DC power supply, Pn001 = n.1 (DC power supply supported) must be selected. Failure to
do so will cause the internal element of the SERVOPACK to burn out, and fire and damage to the devices
may result.
Check the parameter setting before using a DC power supply.
