6.4 About Parameters
To program the drive for a specific application, you adjust the appropriate parameters. The
parameters are used to define characteristics of the drive.
There are three types of parameters:
• Numbered List Parameters (Enumerated Parameters)
Numbered list parameters allow a selection from two or more options. Each item is
represented by a number.
Example: Start/Stop Source (P38)
• 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: Terminal Status Display (d7)
• Numeric Parameters
These parameters have a single numerical value (for example, 0.1 volts).
Example: Motor Rated Current (P32)
Parameters are also either configurable or tunable, or read-only.
Configurable parameters can be adjusted or changed only while the drive is stopped.
