SCANport Command Interface 4-7
Rotation Direction - The rotation direction bit is used to identify the
direction of motor rotation.
Manual Reference Selected - Whenever the digital or SCANport
interfaces select the manual reference the drive acknowledges this
state by setting the manual reference selected bit 15, SCANport Output
Status Word.
The table below describes the fixed assignments for the eight 16 bit
input data words and the eight 16 bit output data words.
SCANport Data Interface
In addition to the SCANport Logic Command word, the SCANport
Logic Status word, the SCANport Command Reference and the
SCANport Feedback Output there are 16 additional 16 bit words
which can be exchanged between an Allen-Bradley PLC and the drive.
