Notes on direct connection with the CPU port of A/Q series CPU

Take appropriate measures to eliminate any noise from entering the communication cable between

the ZM-

and MITSUBISHI A/QnA series CPU.

Noise should be considered when wiring in an electric box or in a machine. Be sure to keep the ZM-

wiring sufficiently away from power cables.

The longer the communication cable is, the more likely noise is to be an influence; therefore, the

cable length should be minimized as much as possible.

File register(R) cannot be used in case of ROM operation of A series CPU.

A noise filter(ferrite core) is sold as an optional accessory.

In consideration of such noise problems, it is recommended that the standard

type link module be used.

Connect to a CPU port.

To secure the noise

filter, attach the cord

band close to its bottom.

According to our noise tests, the attachment of a ferrite core improves noise voltage

by 650 to 900V and aids in preventing communication errors. For safer operation,

be sure to attach the ferrite core to the cable.
