(4) DC Power Supply Input
When using the main circuit power supply input of the SGDH SERVOPACK with DC power supply, use the fol-
lowing power supply and set the parameter Pn001.2 to 1. Also, read carefully to the following ‘Important’ sec-
tion.
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.
(a) Main Circuit and Control Power Supply Input
The following shows the connection for the main power supply and the control power supply.
(b) Setting Parameters
• SGDH SERVOPACK is applicable for both AC and DC power supply input excluding 7.5-kW control 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.

Parameter Meaning
Pn001 n.†0†† Not applicable for main circuit DC power supply input: Input the AC power sup-
ply for the terminal L1, L2 or L3.
n.†1†† Applicable for main circuit DC power supply input: Input the DC power supply
between the terminal
and the terminal 1, or the terminal and the termi-
nal .
• When changing the parameters, turn the power ON again for the necessity of the effective setting.
