AC890PX AC Drive
Programming with Block Diagrams
You can program the drive to your specific application. This programming simply involves changing parameter values. For
instance, parameter
S
1 selects the main method of motor control used by the drive: Volts/Hz or Sensorless Vector.
Block diagram programming provides a visual method of planning the software to suit your application. The blocks described
here are those blocks used by the Shipping Configuration(s) in the DSE 890 Configuration Tool. A typical block diagram as
seen in the DSE 890 Configuration Tool is shown below.
The processes performed by the shipping configuration 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.
