Reading (03) Logic Status
Data
The PowerFlex 520-series drive Logic Status data can be read through the
network by sending Function Code 03 reads to register address 2100H (Logic
Status). PowerFlex 523 drives support only Velocity bit definitions.
PowerFlex 525 drives can use Parameter
C122 [Cmd Stat Select] to select either
Velocity or Position bit definitions.
