(4) DC Power Supply Input
When using the SGDH SERVOPACK with DC power supply input, use the following power supply and set the
parameter Pn001.2 for ‘1’. Also, read carefully to the following ‘Important’ section.
(a) Main Circuit and Control Power Supply Input
The following shows the connection for the main power supply and the control power supply.
1. Servomotor returns the regenerative energy to the power supply when regenerating. SERVOPACK does
not regenerate with DC power supply input specifications, so regenerate the energy on the power supply
side.
2. Take appropriate measures to ensure that a high charging current stays inside the SERVOPACK when
power is OFF.
• Do not use a DC power supply for 100V SERVOPACK SGDS-F
A DC power supply will destroy the SERVOPACK, which may cause a fatal accident or fire.
Do not change the factory setting for Pn001, which is preset to ZERO (n.
000), indicating that “DC power supply
input not supported”.
• 200V SERVOPACK SGDS-
A is applicable for both AC and DC power supply input.
However, if the DC power supply input supplies a voltage without setting ‘Pn001 = n.
1’ (for DC power
supply input), the SERVOPACK’s internal elements will burn and may cause fire or malfunction.
When using the SERVOPACK with DC power supply input, confirm the following setting of parameters.
