Input of upper speed threshold for adaptation of the speed controller machine data. When the
adaptation function is active, the control machine data MD 1408 and MD 1410 are applied at
speeds n > MD 1412. In the medium range MD 1411 < n < MD 1412, linear interpolation
takes place between the two control machine data sets.
See machine data "Adaptation lower speed threshold" (MD 1411) for diagram.

This machine data allows adaptation of the speed controller machine data to be controlled as a
function of speed.
Input 0: The adaptation function is not active. The settings in control machine data
MD 1407 and MD 1409 are applicable over the entire speed range. Control
machine data MD 1408 and MD 1410 are not taken into account.
Input 1: The adaptation function is active. See machine data MD 1411 and MD 1412 for
description.
