7-2-6 Connection of feedback cable
Peel the sheath of the feedback cable where indicated below to expose the shield cover. Ground this
section with a cable clamp, etc. Normally, only the cable to which the scale is connected is grounded
on the servo amplifier side or I/F unit side. However, if the distance between the servo amplifier and
scale I/F unit is 5m or more, also ground this cable.

<Required depending on
conditions>
If the distance between the servo
amplifier and scale I/F unit is 5m
or more, peel the cable sheath at
a point near the servo amplifier,
and ground with a cable clamp.
This also applies when
