Programming Basics
To program the drive for a specific application, you adjust the appropriate
parameters. The parameters are used to define characteristics of the drive.
This chapter provides an overview of parameter types and how they are
organized. Parameter descriptions are provided in
Chapter 9 .
About Parameters There are three types of parameters:
Parameters are also either configurable, tunable, or read-only:
Numbered List
Parameters Numbered list parameters allow a selection from
two or more options. The OIM displays a text
message for each item.
Example: inverter Speed Ref A Sel (90)
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.
Example: inverter Drive Status 1 (209)
Numeric Parameters These parameters have a single numerical value
(for example, 0.1 V).
Example: inverter Maximum Freq (55)
Configurable Parameters Can be adjusted or changed only while the drive is
stopped.
Tunable Parameters Can be adjusted or changed while the drive is
running or stopped.
Read-only Parameters Cannot be adjusted.
