Description:
The adaptation acceleration value is only required if "Friction compensation with
adaptation" (MD32510=1) is active.
The adaptation acceleration values 1 to 3 are interpolation points for defining the
adaptation curve. The adaptation curve is subdivided into 4 ranges, in each of which
a different friction compensation value applies.
For the 1st range (a < MD32550), the add-on amplitude = a * MD32520/ MD32550
MD irrelevant for:
MD32510 $MA_FRICT_COMP_ADAPT_ENABLE = 0

Description:
The adaptation acceleration value is only required if "Friction compensation with
adaptation" (MD32510 $MA_FRICT_COMP_ADAPT_ENABLE=1) is active.
Adaptation acceleration values 1 to 3 are interpolation points for defining the
adaptation curve. The adaptation curve is subdivided into 4 ranges, in each of which
a different friction compensation value applies.
In the 1st acceleration range (
MD32520 * (a/MD32550).
In the 2nd acceleration range (MD32550 <= a <= MD32560), the switching amplitude =
MD32520.
In the 3rd acceleration range (MD32560 <
MD32520 + (MD32530-MD32520)/(MD32570-MD32560) * (a - MD32560).
In the 4th acceleration range (MD32570 <= a
MD32530.
