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 4.
3.1 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.
