14.5 Measures for Various Cables
The various cables act as antennas for the noise and discharge the noise externally. Thus appropriate treatment is required to
avoid the noise.
The wiring between the drive unit and motor act as an extremely powerful noise source, so apply the following measures.
14.5.1 Measures for Wiring in Panel
[1] If the cables are led unnecessarily in the panel, they will easily pick up the radiated noise. Thus, keep the wiring
length as short as possible.
[2] The noise from other devices will enter the cable and be discharged externally, so avoid internal wiring near the
openings.
[3] Connect the control device earthing terminal and earthing plate with a thick wire. Take care to the leading of the
wire.
14.5.2 Measures for Shield Treatment
Common items
Use of shield clamp fittings is recommended for treating the shields. The fittings are available as options, so order as
required. (Refer to the section "Shield Clamp Fitting" in this chapter.)
Clamp the shield at a position within 10cm from the panel lead out port.
POINT
1. When leading the cables, including the grounding wire (FG), outside of the panel, clamp the cables near the panel outlet
(recommendation: within 10cm).
2. When using a metal duct or conduit, the cables do not need to be clamped near the panel outlet.
3. When leading cables not having shields outside the panel, follow the instructions given for each cable. (Installation of a
ferrite core, etc., may be required.)
