Shield Clamping Of Cables - Mitsubishi Electric MELDAS 600 Series Connection Manual

3.3.2 Shield Clamping of Cables

The shield cable connected to the control unit, servo amplifier and spindle amplifier 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, with clamp fittings or with the
connector GNP plate. Refer to the following drawings to treat the shield cable.
Lead wire treatment method

method
Fold the cable shield over the sheath, and wrap copper foil tape around it. Connect the wound
copper foil tape to the connector's GND plate.
(1) Peel part of the cable sheath and expose the shield as
shown in the drawing.
Press the exposed part against the grounding plate with
the cable clamp fittings.
(2) If the cable is thin, clamp several together in a bunch.
(3) Use adequate force when tightening the cable so that
the wire material is not damaged.
(4) Connect each grounding plate together and ground
them at one point.
Refer to APPENDIX 1 about the outline drawing of clamp fittings and grounding plate.
