VI/S3 Input terminal selection 5 (VI/S3) 5～17 8 (preset speed 3)
Note 1: The parameter (always active function selection) allows you to select a function
you want to keep always active.
Note 2: The parameter (input terminal selection 5 (VI/S3)) is enabled only when is
set to 2.
It is necessary to insert an adequate resistor* between P15 and VI/S3.
(*Recommended resistance : 4.7kΩ-1/4W)

2) Connection with transistor output (Sink logic)
★Operation can be controlled by connecting the input and
CC (common) terminals to the output (non-contact switch)
of a programmable controller. This function is used to
specify forward/reverse run or preset speed operation.
Use a transistor that operates at 15Vdc-5mA.

* Interface between inverter and programmable controller
When an open collector output type programmable controller is being used for operation
control, turning off the programmable controller with the inverter left ON causes a wrong signal
to flow into the inverter, as shown in the figure below, because of a difference in control power
potential. To avoid this, be sure to interlock the inverter and the programmable controller so
that the programmable controller cannot be turned off when the inverter is on.

• Function
These parameters are used to specify a function for each individual input terminal. With these
parameters allowing selection from among 45 functions for each input terminal, you can
design a system with great flexibility. (For (input terminal selection 5), you can make a
selection from among 13 functions.)
*1 Using the parameter, you can select a function between analog input (frequency
command input) and contact input for the VI/S3 terminal. The VI/S3 terminal is set by default
as a voltage signal input terminal. When using the VI/S3 terminal as a contact input terminal,
you need to set to 2 (contact input enabled), and then to specify a contact input
function for it, using , because it is set by default as a voltage signal input terminal.
Note: Do not set parameter if VI/S3 terminal is not used as contact input.
