- Page 31 Using Intelligent Input Terminals Terminals [1], [2], [3], [4], [5], [6] and [7] are identical, programmable inputs for general use. The input circuits can use the inverter’s internal (isolated) +24V field supply or an external power supply. This section describes input circuits operation and how to connect them properly to switches or transistor outputs on field devices.
- Page 32 The two diagrams below input wiring circuits using the inverter’s internal +24V supply. Each diagram shows the connection for simple switches, or for a field device with transistor outputs. Note that in the lower diagram, it is necessary to connect terminal [L] only when using the field device with transistors.
- Page 33 The two diagrams below show input wiring circuits using an external supply. If using the “Sinking Inputs, External Supply” in below wiring diagram, be sure to remove the jumper wire, and use a diode (*) with the external supply. This will prevent a power supply contention in case the jumper wire is accidentally placed in the incorrect position.
- Page 34 CAUTION: Be sure to connect diode in between "P24" and "PLC" when connecting plural inverters with digital input wiring in common. By having ability inverter doesn’t block the current flowing into itself when it is not powered. This may cause the closed circuit when two or more inverters are connected to common I/O wiring as shown below to result in unexpected turning the on the input.
- Page 35 Forward Run/Stop and Reverse Run/Stop Commands: When you input the Run command via the terminal [FW], the inverter executes the Forward Run command (high) or Stop command (low). When you input the Run command via the terminal [RV], the inverter executes the Reverse Run command (high) or Stop command (low).

- Page 38 Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that automatic startup, so that the inverter will not run without outside intervention. When USP is active and you need to reset an alarm and resume running, either turn the Run command OFF, or perform a reset operation by the terminal [RS] input or the keypad Stop/reset key.
- Page 39 Reset Inverter The [RS] terminal causes the inverter to execute 12 ms the reset operation. If the inverter is in Trip Mode, minimum [RS] the reset cancels the Trip state. When the signal [RS] is turned ON and OFF, the inverter executes Approx.

- Page 41 Frequency Arrival Signals The Frequency Arrival group of outputs helps coordinate external systems with the current velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output frequency arrives at the standard set frequency (parameter F001). Output [FA2] relies on programmable accel/ decel thresholds for increased flexibility.
