Red: Reference frequency response speed controller with differential position feedback
Figure 9-44 Effect on the speed controller reference frequency response
As a result of the differential position feedback, the resonant position is shifted to a higher
frequency. The damping effect of the speed controller is increased with the same controller
gain.

Important notes for parameterization

● The functions always require a direct measuring system. If an axis is equipped with a
measuring system (encoder 2 or encoder 3), then this can be selected using p3701. BICO
sink p3749 can be activated by setting p3700.9 = 1. The load speed actual value can now
be freely interconnected, e.g. from a master axis.
● The encoder combination is activated using p3700.8 = 1. Position differential feedback is
activated using p3700.0 = 1.
Note
If APC was parameterized (p3760, p3761, p3765, p3766 > 0), then this is also activated. If
necessary, these parameters must be set to "0".
