The 400V model SERVOPACK has mounting space specifications for multi-axis cabinet installations which do not require space between SERVOPACKs that are mounted side-by-side.

However, space is required for the end SERVOPACKs to provide adequate air movement in a cabinet. (See last picture in Resolution section)

Follow the guidelines below when mounting Sigma 7 SERVOPACKs inside of a cabinet.

Installing One SERVOPACK in a Control Panel

The 200V and 400V Sigma 7 SERVOPACKs have the same space requirements when mounting only ONE SERVOPACK inside a cabinet or control panel.

Installing More than One SERVOPACK in a Control Panel

The 200V and 400V Sigma 7 SERVOPACKs have different space requirements when mounting more than one inside a cabinet or control panel.

Note that the top and bottom distances may vary. Refer to the relevant user's manuals for additional information.

The 400V Sigma 7 SERVOPACKs has no space requirement inbetween SERVOPACKS, but does have a space requirement along the sides.

Note: 

• Install cooling fans above the SERVOPACKs so that hot spots do not occur.
• Yaskawa does NOT sell cabinet fans as shown in the picture. They are for reference only.
