MDI_ACC (MDI acceleration)
This process data defines the acceleration for MDI sets.
Normalization: 4000 hex (16384 dec) = 100 %
The value is restricted to 0.1 ... 100% internally.
MDI_DEC (MDI deceleration override)
This process data defines the percentage for the deceleration override for MDI sets.
Normalization: 4000 hex (16384 dec) = 100 %
The value is restricted to 0.1 ... 100% internally.

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)

Meaning
0 = Relative positioning is selected
1 = Absolute positioning is selected
0 = Absolute positioning through the shortest distance
1 = Absolute positioning in the positive direction
2 = Absolute positioning in the negative direction
