NOTE
In the following cases, use optical fiber cable connection
through an optical I/O link adapter.

D When the power magnetics cabinet where the spindle
amplifier is installed and the operator’s panel cabinet where
the CNC control unit is installed cannot be connected
through a grounding wire of 5.5 mm
2
or more.
D When the cable may be affected by noise.
For instance, this applies when there is a source of strong
magnetic noise, such as a welder, near the cable or when
the cable is routed, for a long distance, in parallel with a
power line or ferroelectric cable which may generate noise.
