  • Page 17: Wiring

    Wiring Use twisted pair shield cables (0.2 mm or larger) to connect the FR-A8AP and position detector. For the wiring to the terminals PG and SD, use several cables in parallel or use a thick cable, according to the wiring length.
  • Page 18 When differential driver is set and a wiring length is 30 m or more The wiring length can be extended to 100 m by slightly increasing the 5 V power supply (approx. 5.5 V) and using six or more cables with gauge size of 0.2 mm in parallel or a cable with gauge size of 1.25 mm or more.
  • Page 19 Wire the shielded twisted pair cable after stripping its sheath to make its cables loose. Also, protect the shielded cable of the shielded twisted pair cable to ensure that it will not make contact with the conductive area. Shield (perform protective treatment) Sheath Shielded twisted pair cable Strip the signal wires as follows.
