Others
When using heat generating equipment such as the regenerative option, install it with full consideration of heat generation so
that the servo amplifier is not affected.
Mount the servo amplifier on a perpendicular wall in the correct vertical direction.
2.2

Keeping out of foreign materials

When drilling the cabinet for assembly, prevent drill chips and wire fragments from entering the servo amplifier.
Prevent oil, water, metallic dust, and others from entering the servo amplifier through openings in the cabinet, or through a
cooling fan installed on the ceiling.
When installing the cabinet in a place where toxic gas, dirt, and dust exist, conduct an air purge (force clean air into the
cabinet from outside to make the internal pressure higher than the external pressure) to prevent such materials from entering
the cabinet.
2.3

Cable stress

The way of clamping the cable must be fully examined so that bending stress and cable's own weight stress are not applied to
the cable connection.
When used for applications where the servo motor moves, fix the cable (encoder, power supply, brake) with gentle slack from
the connecting part of the connector, to prevent stress from being applied to the connecting part of the servo motor connector.
Use the optional motor cable/encoder cable within the bending life range.
Prevent the cable insulator from being cut by sharp chips or from touching and rubbing against the machine corners.
Prevent the cables from getting stepped on by workers or run over by vehicles.
For installation of servo motor on the machine that moves, the flexing radius should be made as large as possible. Refer to
the following for the bending life.
Page 127 Cable bending life
Precautions
• The cables should not be damaged, stressed, loaded, or pinched.
