7.8.21.3 Object 0x550A: State feedback axis acceleration proportional gain
The second derivation of the axis position value (or the derivation of the #VelFeedBack#) is the acceleration
feedback. To realize a state space controller, this second derivation multiplied with the
<ProportionalFeedBackGainKa> (0x550A) will be added to the other parts of the controller.

7.8.22 Directional depending gain
To compensate a not symmetrical movement between moving in and out a directional depending gain is im-
plemented.
Figure 112: Directional depending gain
7.8.22.1 Object 0x550D: Directional depending positive proportional gain
This gain is used while the input signal is positive.
7.8.22.2 Object 0x550E: Directional depending negative proportional gain
This gain is used while the input signal is negative.
