16-12 16. MITSUBISHI ELECTRIC PLC
Wiring Diagram 8
According to our noise tests, the attachment of a ferrite core improves noise voltage by 650 to 900 V and aids in
preventing communication errors.
• When connecting to the A/QnA series CPU directly, attach a ferrite core to the communication cable between
the V7 series and A/QnA series CPU to avoid noise problems.
• Ferrite cores are optionally available.
When ordering the ferrite core, state “GD-FC (ID: 8 mm, OD: 20 mm).”
• In consideration of such noise problems, it is recommended that the standard type link unit be used when the
cable length of 15 m or longer is required.
