Reference model

Description
The reference model is activated with p1400.3 = 1.
The reference model is used to emulate the speed control loop with a P speed controller.
The loop emulation can be set in p1433 to p1435. It becomes effective if p1437 is connected
to the output of the model r1436.
The reference model delays the setpoint-actual value deviation for the integral component of
the speed controller so that settling (stabilizing) operations can be suppressed.
The reference model can also be externally emulated and the external signal entered via
p1437.
