(c)CC-Link module

MELSEC-Q

1)Be sure to ground the cable shield that is connected to the CC-Link module close to the exit of control panel or to any of the CC-Link stations within 30 cm (11.81 inch) from the module or stations.

The CC-Link dedicated cable is a shielded cable. As shown in the illustration below, remove a portion of the outer covering and ground as large a surface area of the exposed shield part as possible.

2)Always use the specified CC-Link dedicated cable.

3)Do not use a ferrite core for the CC-Link module or CC-Link stations.

4)The CC-Link module, the CC-Link stations and the FG line inside the control panel should be connected at both the FG terminal and the SLD terminal as shown in the diagram below.

(d) I/O signal lines

For the I/O signal lines, if extracted to the outside of the control panel, also ensure to earth the shield section of these lines and cables in the same manner as in item (1) above.

(2) Power supply module

The precautions required for each power supply module are described below.

Always observe the items noted as precautions.

Model

Precautions

A1S61P

Not usable

A1S62P

 

A1S63P ( 1)

Use the CE marked 24VDC panel power equipment.

A1S61PEU

 

A1S62PEU

Always ground the LG and FG terminals after short-circuiting them.

A1S61PN

 

A1S62PN

 

( 1) If sufficient filter circuitry is built into the 24VDC external power supply module, the noise generated by A1S63P will be absorbed by that filter circuit, so a line filter may not be required.

Filtering circuitry of version F or later of A1S63P is improved so that a external line filter is not required.
