Converter Part Names

This section describes the parts of a converter.
Use a converter together with a SERVOPACK. For details, refer to 1.9 Combinations of Servomotors, SER-
VOPACKs, and Converters.
Note: For the purpose of this description, the SERVOPACK is shown with the front cover removed. Always keep the front
cover attached when using the SERVOPACK.

Name
Indicates the converter model and ratings. Located
on the side of the converter.
Used to connect the control power input.
These connectors output 24 VDC to the SERVO-
PACK. For a 400-V system, the 24-VDC (±15%)
input is output unaltered from CN103. CN103 and
CN104 are equivalent outputs. It is normally not
necessary to connect CN104.
Connect this connector to CN901 on the converter. –
Lights (orange) when the main circuit power sup-
ply is ON and stays lit as long as the internal
capacitor remains charged. Therefore, do not touch
the SERVOPACK even after the power supply is
turned OFF if the indicator is lit. It may result in
electric shock.
Connects a DC reactor for harmonic suppression.
1 and 2)
Used for main circuit power supply input.
Be sure to connect to protect against electrical
shock.
