Chapter 1 - FUNCTION DESCRIPTION

1.1 GENERAL CONSIDERATIONS

The drive control diagram is made of functional Blocks each representing a part of the total function. For
example speed regulator, ramp etc., each containing some Variables, the gains, the ramp times, the limits etc.
The input and / or output of Blocks are interconnected to make the complete system function. Such interconnec-
tions are called SIGNALS.
The setting of the Drive parameters/variables can be performed via the keypad or a PC Configurator.
The structure of the menu functions is the following:
src
(Source)
cfg
(Configuration)
mon
(Monitor)
The three above elements are inside a menu, as needed by each single Block.
Example Block:
Input selected
An out 1 src

This chapter describes:
· Variable connection methods
· Block functions
· Signal normalization

These are parameters that select where an input comes from. The
selections are from a pick-list.
The source is aimed at controlling (or enabling) the Block inputs.
These are parameters that define how the function or parameter acts. For
example: Ramp times, internal references adjustments.
Signals in this menu are variables. They are read only, and show the value or
state of a signal.
