Wiring Control Circuit Terminals2- 23Wiring Control Circuit Terminals Wire Sizes and Closed-loop ConnectorsFor remote operation using analog signals, keep the control line length between the Digital Operator or opera-tion signals and the Inverter to 50 m or less, and separate the lines from high-power lines (main circuits orrelay sequence circuits) to reduce induction from peripheral devices.When setting frequencies from an external frequency setter (and not from a Digital Operator), use shieldedtwisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.Fig 2.17Terminal numbers and wire sizes are shown in Table 2.9.* 1. Use shielded twisted-pair cables to input an external frequency reference.* 2. Refer to Table 2.3 Close-loop Connector Sizes for suitable closed-loop crimp terminal sizes for the wires.* 3. We recommend using straight solderless terminal on signal lines to simplify wiring and improve reliability.Table 2.9 Terminal Numbers and Wire Sizes (Same for all Models)TerminalsTermi-nalScrewsTighteningTorque(N•m)PossibleWire Sizesmm 2 (AWG)Recom-mendedWire Sizemm 2 (AWG)Wire TypeFM, AC, AM, P1, P2, PC,SC, A1, A2, , +V, ,S1, S2, S3, S4, S5, S6, S7,, MA, MB, MC, M1,M2M3.5 0.8 to 1.0 0.5 to 2*2(20 to 14)0.75(18)• Shielded, twisted-pair wire*1• Shielded, polyethylene-cov-ered, vinyl sheath cable(KPEV-S by Hitachi ElectricalWire or equivalent)MP, RP, R+, R-, S+, S-,IG Phoenixtype 0.5 to 0.6Single wire *3:0.14 to 2.5Stranded wire:0.14 to 1.5(26 to 14)0.75(18)E (G) M3.5 0.8 to 1.0 0.5 to 2*2(20 to 14)1.25(12)PPPPE(G)Shield terminalV Speed setting powersupply +15 V 20 mAA1 Master speed reference 0 to 10 V (-10 to 10 V)A2 Master speed reference 4 to 20 A(0 to 10 V, -10 to 10 V)A3 Auxiliary reference 0 to 10 V (-10 to 10 V)RP Pulse train input 32 kHz max.AC Analog common2kΩ2kΩ2kΩ2kΩ-V Speed setting power supply -15 V 20 mAA3 -VS8
