Note
Changing parameter p5300 changes parameters p5280 and p1400. Therefore after
deactivating the autotuning function check the accuracy of the configuration of parameters
p5280 and p1400 and amend these if required.

Effect
The speed controller gain is determined and set with the aid of a noise signal.
Any required current setpoint filters are determined and set with the aid of a noise signal. In
this way, a higher dynamic response can be achieved in the speed control loop.
With this bit, the moment of inertia is determined with the aid of a test signal. If this bit is not
set, the load moment of inertia must be parameterized manually in parameter p1498. The
test signal must first be set with parameters p5308 and p5309.
Possibly existing load oscillations (low-frequency resonance) are determined using a test
signal. The function detects frequencies in the range of approx. 2Hz to 95Hz. No external
measuring system is required for the load. The frequencies detected (zero positions and
pole positions) are displayed in p5294[0...2] and p5295[0...2]. A sufficiently large traversing
distance must be preset using parameter p5308 for this function.
In addition to the loan oscillation detection (see bit 04) an active attenuation is configured
for the load oscillation detected. In doing so, the frequency of the smallest zero position is
automatically entered in p3752. A requirement for this is the function module "Advanced
Positioning Control" (r0108.7 = 1) and p3700.2 = 1. The load moment of inertia must also
be determined using p5301.2 - or first manually entered in p1498.
After the function is performed, Advanced Positioning Control must be activated by setting
p3700.0 to 1.
With this function, these axes are adapted to the dynamic response set in p5275. This is
required for interpolating axes. The time in p5275 should be set with the lowest dynamic
response in accordance with the axis.
