Adaptive Program

Chapter overview

The chapter describes the basics of the Adaptive Program and instructs in building a
program.

What is the Adaptive Program

Conventionally, the user can control the operation of the drive by parameters. Each
parameter has a fixed set of choices or a setting range. The parameters make the
programming easy, but the choices are limited: you cannot customise the operation
any further. The Adaptive Program makes freer customising possible without the
need of a special programming tool or language:

• The program is built of function blocks.

• The control panel is the programming tool.

• The user can document the program by drawing it on block diagram template

sheets.

The maximum size of the Adaptive Program is 15 function blocks. The program may
consist of several separate functions.
