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 12.
11.1 About Parameters
There are three types of parameters:
• Numbered List Parameters
Numbered list parameters allow a selection from two or more
options. The LCD OIM displays a text message for each item.
Example: 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: Drive Status 1 (209)
• Numeric Parameters
These parameters have a single numerical value (for example,
0.1 volts).
Example: Maximum Freq (55)
Parameters are also either configurable or tunable, or read-only.
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.
