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 C onfiguration 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.
