Description:
1:
errors on circular contours can be compensated with friction compensation.
The amplitude of the friction compensation value required to be added on is frequently
not constant over the entire acceleration range. That is, a lower compensation value
needs to be entered for optimum friction compensation for higher accelerations than
for lower accelerations.
The parameters of the adaptation curve have to be determined, and entered in the
machine data.

Description:
If adaptation is inactive (MD32510 $MA_FRICT_COMP_ADAPT_ENABLE=0), the maximum
friction compensation is applied throughout the entire acceleration range.
If adaptation is active (MD32510 $MA_FRICT_COMP_ADAPT_ENABLE=1), the maximum friction
compensation is applied in accordance with the adaptation curve.
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).
