Manual(s): PowerFlex 4, PowerFlex 40

The PowerFlex 4 and PowerFlex 40 Drive Codes Are nearly Identical in both parameters and faults so for simplicity they both share one page. The Display group can be used for both monitoring the heath of the motor and drive or to troubleshooting problems that occur. The Parameters group is used to configure drive operations. The Fault group is used to translate codes given by the drive when problems are detected.
