FB - Field Bus Parameters
FB01-04: Processed PDI Data
After the raw PDI Data (FB34-37) has been received from the controller, it
may be masked or scaled (FB05-09), depending on which function (FB01-04:
Control Word, Speed, Pretorque, Target Position) the data is mapped to via the
PDI Map Assignments (FB17-20). The PDI Map Assignments will be chosen
according to the order of each function’s data within the telegram structure.
Read-only display of processed eld bus control word in hexadecimal.
FB01 = PDI Data (Control Word) AND FB05 Field Bus Control Word Mask.
Refer to LI15, Direction Selection Inputs setting on how the hardware and
software inputs are ANDed or ORed.
Read-only display of processed eld bus speed command, where 1 = 0.1 FPM.

PDI Data (Speed) is the FB34-37 parameter corresponding to speed,
depending on the telegram structure. If the FB17-20 PDI Map Assignments
are set according to the telegram structure, then they can be used to determine
which corresponding FB34-37 PDI Data is used as raw data from the controller
for speed.
Read-only display of pretorque, where 1 = 1%. Additionally LA15 Analog Input
2 Gain and LA17 Analog Input 2 Offset can be applied to this value when LC01
= Digital Pretorque (4). Refer to section 6.13 for additional information.
FB03 = PDI Data (Pretorque)
Processed Pretorque Value = (FB03 + LA17) * LA15
