Chapter 3
Programming and Parameters
Chapter 3 provides a complete listing and description of the PowerFlex 
40P parameters. Parameters are programmed (viewed/edited) using 
either a DSI Remote HIM or PC programming tools (DriveExplorer™ or 
DriveTools SP™ software), a personal computer and a serial converter 
module. Refer to Appendix
 B for catalog numbers. 
To configure a drive to operate in a specific way, drive parameters may 
have to be set. Three types of parameters exist:
• ENUM
ENUM parameters allow a selection from 2 or more items. Each item 
is represented by a number.
• Numeric Parameters
These parameters have a single numerical value (i.e. 0.1 Volts).
• Bit Parameters
Bit parameters have four 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.
Some parameters are marked as follows.
