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 recalls a pre-programmed set of default parameters and links when it is loaded.
Refer to Chapter 5: “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. These pages replicate the ConfigED Lite
programming screens. ConfigEd Lite is Parker SSD Drive’s own programming tool.
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 instance of a 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:
C
onfiguration
and
Parameterisation
modes.
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.
When you attempt to change a parameter value requiring Configuration Mode to be
enabled, the Operator Station immediately displays ENABLE CONFIG. Refer to
Figure 1-1, page 1-2. Press the
E
key at this point if you do not want to enter
Configuration Mode. Press the
V
(up) key as instructed to enter Configuration Mode.
This is indicated by all LEDs flashing.
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.
Once in Configuration Mode, to return to Parameterisation Mode simply press the
E
key repeatedly until the Welcome screen is displayed. Press the
E
key again and
Configuration Mode will be disabled. This is indicated by LEDs ceasing to flash.
