Using Intelligent Input Terminals

Wiring Diagram Conventions

The input wiring diagrams in this chapter are examples only. Default and non-default input terminal assignments are noted throughout; your particular assignments may be different. The wiring diagrams show the –xFU/–xFR model default [P24]–[PLC] jumper position (U.S./Jpn versions), as shown below on the left. The common (return) for inputs is [CM1] in this case. The diagram on the right shows the default jumper position and example input wiring for –xFE models (Europe version). For this case, the common (return) for inputs is [P24]. Be sure the

jumper position and return terminal used match your application wiring needs.

When you input the Run command via the dedicated terminal [FW], the inverter executes the Forward Run command (high) or Stop command (low). When you input the Run command via the programmable terminal [RV], the inverter executes the Reverse Run command (high) or Stop command (low).

NOTE: The parameter F004, Keypad Run Key Routing, determines whether the single Run key issues a Run FWD command or Run REV command. However, it has no effect on the [FW] and [RV] input terminal operation.

WARNING: If the power is turned ON and the Run command is already active, the motor starts rotation and is dangerous! Before turning power ON, confirm that the external Run command is not active.
