INSTALLATION 2.4 (1) Wiring Use twisted pair shield cables (0.2mm2 or larger) to connect the FR-A7AP and position detector. To protect the cables from noise, run them away from any source of noise (e.g. the main circuit and power voltage). Wiring Length Paralell Connection Within 10m At least 2 cables Within 20m At least 4 cables Within 100m * At least 6 cables Larger-Size Cable Cable gauge 0.2mm2 0.4mm2 or larger 0.75mm2 or larger 1.
INSTALLATION (2) Connection with the NC (numerical controller) When one position detector is shared between the FR-A7AP and NC, its output signal should be connected as shown on the right. In this case, the wiring length between the FR-A7AP and NC should be as short as possible, within 5m.
INSTALLATION (3) Wire the twisted pair shielded cable after stripping its sheath to make its cables loose. Also, protect the shielded cable of the twisted pair shielded cable to ensure that it will not make contact with the conductive area. Wire the stripped cable after twisting it to prevent it from becoming loose. Cable stripping size In addition, do not solder it. Use a bar type terminal as required. 5mm REMARKS Information on bar terminals Introduced products (as of August, 2005): Phoenix Contact Co.
INSTALLATION (5) For wiring of 22K or less, remove a hook of the front cover and use a space become available. For wiring of 30K or more, use the space on the left side of the control circuit terminal block. Cut off with a nipper, etc. Cut off a hook on the inverter front cover side surface. (Cut off so that no portion is left.
