‹ Wire Gauges and Closed-Loop Connectors For remote operation using an analog signal, keep the control line length between the digital operator or oper- ation signals and the MxC to 50 m or less, and separate the lines from high-power lines (main circuits or relay sequence circuits) to reduce induction from peripheral devices. When setting frequencies from an external device (i.e., not from the digital operator), use shielded twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram. Fig 2.14 Terminal numbers and wire gauges are shown in Table 2.6 . Table 2.6 Terminal Numbers and Wire Gauges (Same for all Models) * 1.
Use shielded twisted-pair cables to input an external frequency reference. * 2. Refer to Table 2.3 Closed-Loop Connector Sizes (JIS C2805) (200 V class and 400 V class) for suitable closed-loop crimp terminal sizes for the wires. * 3. Yaskawa recommends using a straight solderless terminal on signal lines to simplify wiring and improve reliability.
