5.2.2 Shield Clamping of Cables
The shield of the shield cable connected to the control unit and drive unit must be connected to the grounding plate to stabilize
operation while preventing malfunctioning due to noise.
The shield can be connected to the grounding plate with lead wires or clamp fittings. Refer to the following drawings to treat
the shield cable.
