Introducing the Macro

You can program the Inverter for specific applications.

The Inverter is supplied with macros (set-ups) which can be used as starting points for

application-specific programming. This programming could simply involve the inputting of

parameter values, or it may require the making or breaking of programmable links, which is a

feature of this unit.

Each macro instantly recalls a pre-programmed set of default parameters when it is loaded.

Refer to Chapter 15: “Application Macros” for further information.

Programming with Block Diagrams

Block diagram programming provides a visual method of planning the software to suit your

application. There are block diagrams provided at the end of this chapter, each showing the

software connections for an application macro.

The processes performed by a macro are represented as a block diagram, consisting of  function

blocks and links:

•  Each function block contains the parameters required for setting-up a particular processing

feature. Sometimes more than one function block is provided for a feature, i.e. for multiple

digital inputs.

•  Software links are used to connect the function blocks. Each link transfers the value of an

output parameter to an input parameter of another (or the same) function block.

Each individual block is a processing feature, i.e. it takes the input parameter, processes the

information, and makes the result available as one or more output parameters.

Modifying a Block Diagram

Configuration and Parameterisation Modes

There are two modes of operation used while modifying a block diagram:

Parameterisation and Configuration modes.

The ENABLE CONFIG and DISABLE CONFIG commands, found under SYSTEM menu at

level 1, is used to toggle between these two modes of operation.

Parameterisation Mode

In parameterisation mode you can change parameter values. The Inverter can be

running or stopped. Note that some parameters can only be changed when the Inverter

is stopped. It is not possible to modify the internal links when the Inverter is in

parameterisation mode.

Configuration Mode

In the configuration mode you can modify the links in the function block diagram. You

can also change parameter values, as above. This mode is indicated by all the LEDs on

the operator station flashing at once. The Inverter cannot run in this mode.

Making and Breaking Links in Configuration Mode

Links can be moved, added or deleted from a block diagram whilst in the Configuration mode.

There are 50 links available, each has its own identification number (“link” number). You make

a link by setting the link’s “source” and “destination” tags to be the two parameter tag numbers

to be linked. The outputs of function blocks are not updated whilst in this mode.
