MDI_MODE
This process data defines the mode for MDI sets.
Precondition: p2654 > 0
MDI_MODE = xx0x hex → Absolute
MDI_MODE = xx1x hex → Relative
MDI_MODE = xx2x hex → Abs_pos (only for modulo correction)
MDI_MODE = xx3x hex → Abs_neg (only for modulo correction)

Note
This chapter describes the assignment and meaning of the process data in SINAMICS
interface mode (p2038 = 0).
The reference parameter is also specified for the relevant process data. The process data
are generally normalized in accordance with parameters p2000 to r2004.
The following scalings also apply:
A temperature of 100°C = 100%
An electrical angle of 90° also = 100%.
