Programming Basics
To program the drive for a specific application, you adjust the appropriate

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.
