Designing a Power ON Sequence
IMPORTANT
Note the following points when designing the power ON sequence.
Harmonic Suppression
If another device requires for harmonic suppression, connect the DC reactor to the DC main circuit side on the
SERVOPACK. For connecting examples, refer to 6.4.8 DC Reactor for Harmonic Suppression.
(3) DC Power Supply Input
• SGDM SERVOPACK is applicable for both AC and DC power supply input excluding 6-kW and 7.5-kW con-
trol 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 main circuit power supply input of the SGDM 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 'Impor-
tant' section.
1. Servomotor returns the regenerative energy to the power supply when regenerating. SERVOPACK does not

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

• Design the power ON sequence so that main circuit power supply is turned OFF when a servo alarm sig-
nal is output. See the previous circuit figure.
• The SERVOPACK will output (1Ry is OFF) a servo alarm signal for two seconds or less when control
power is turned ON. This is required in order to initialize the SERVOPACK.
