Description: Displays the velocity pre-control value after symmetrizing for the force build-up (emulates the closed current control
loop).
Dependency: Symmetrizing can be parameterized with p1428 and/or p1429.
Description: Sets the natural frequency of a PT2 element for the reference model of the speed controller.
Recommend.: The reference model is correctly set when the characteristics of p1439 (reference model output) and p1445 (actual
speed value) are virtually identical when the I-component of the speed controller is disabled.
Dependency: Together with p1434 and p1435, the characteristics (in the time domain) of the closed-loop speed control (P) can be
emulated.
For VECTOR (r0107) the following applies:
The reference model is activated with p1400.3 = 1. For sensorless vector control (p1300 = 20) the reference model
is disabled in open-loop speed controlled operation (refer to p1755).
Refer to: p1434, p1435
Description: Sets the natural frequency of a PT2 element for the reference model of the velocity controller.
Recommend.: The reference model is correctly set when the characteristics of p1439 (reference model output) and p1445 (actual
velocity value) are virtually identical when the I-component of the velocity controller is disabled.
Dependency: Together with p1434 and p1435, the characteristics (in the time domain) of the closed-loop velocity control (P) can
be emulated.
Refer to: p1434, p1435
Description: Sets the damping of a PT2 element for the reference model of the speed controller.
