Toshiba VF-nC1 instruction manual Using other speed commands with preset speed command, Eoqf

E6581090

☆SS3 (preset speed 3) and SS4 (preset speed 4) are not assigned to any terminals at the factory. Before use, therefore, assign SS3 and SS4 to reserved terminals, using the input terminal function selection parameter. In the above example, these functions are assigned to the R and VI/S3 terminals.

[Example of a connection diagram] (When the input terminals are placed in sink logic mode)

*1 : When using the VI/S3 terminal as a contact input terminal, be sure to insert a resistor* between the P15 and VI/S3 terminals. (* Recommended resistance: 4.7kΩ-1/4W)

Note) The preset speed command is always given priority when other speed commands are input at the same time.

Below is an example of 3-step speed operation with standard default setting.
