Wiring Control Circuit Terminals
‹ Wire Sizes and Closed-loop Connectors
For remote operation using analog signals, keep the control line length between the Digital Operator or
operation signals and the Drive to 50 m (164 ft) 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 frequency reference (and not from a Digital Operator), used
shielded twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.
Fig 2.13
Terminal numbers and wire sizes are shown in Table 2.9.
* 1. Use shielded twisted-pair cables to input an external frequency reference.
* 2. Yaskawa recommends using straight solderless terminals on digital inputs to simplify wiring and improve reliability.
* 3. Yaskawa recommends using a thin-slot screwdriver with a 3.5 mm blade width.
