Programming and Parameters
This chapter provides a complete listing of the PowerFlex DC drive parameters.
The list contains a description, default value, minimum and maximum values,
units, and data type for each drive parameter. The parameters can be viewed and
edited (programmed) using a Human Interface Module (HIM). As an
alternative, programming can also be performed using DriveExplorer™,
DriveTools™ SP
(1)
, or Connected Components Workbench™ software
(2)
and a
for a brief description of the LCD HIM. See
for drive control block diagrams.
About Parameters
To configure a drive to operate in a specific way, certain parameters may need to
be changed from the default value. Three types of parameters exist:
• ENUM Parameters
ENUM parameters allow a selection from two or more items. The LCD
HIM will display a text message for each item.
• Bit Parameters
Bit parameters have individual bits associated with features or conditions.
If the bit is “0”, the feature is off or the condition is false. If the bit is “1”, the
feature is on or the condition is true.
• Numeric Parameters
These parameters have a single numerical value and unit (for example, 0.1
Volts).
The example on the following page shows how each parameter type is presented
in this manual.
