7.2.3 Typical Main Circuit Wiring Examples
(4) DC Power Supply Input
• SGDH SERVOPACK is applicable for both AC and DC power supply input.
However, if the DC power supply input supplies a voltage without setting '1' (for DC power supply input) in
the parameter Pn001.2, 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.
When using the SGDH SERVOPACK with DC power supply input, use the following power supply and set the
parameter Pn001.2 to 1. Also, read carefully to the following 'Important' section.
1. Servomotor returns the regenerative energy to the power supply when regenerating. SERVOPACK does

2. Take appropriate measures to ensure that a high charging current stays inside the SERVOPACK when
