Activating autotuning
You can configure the activation and deactivation of the autotuning function via parameter
p5300.
The following settings are possible:
Setting
-1
0
1
2
Note
Changing the parameter p5300 manipulates the 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.
Configuring the "One button tuning"
The following settings are possible via p5301:

Explanation
The "Autotuning" function is set inactive. The setting is automatically corrected to
p5300 = 0. The default settings for the speed controller and position controller are also
restored.
The "Autotuning" function is set inactive. The current setting of all controller
parameters are retained as volatile values. The parameters must be saved in the non-
volatile memory for permanent storage of the values determined for the speed
controller and position controller (p0977 = 1).
The "One button tuning" function is active. A new calculation of the controller
parameters is performed once. p5300 = 0 is then set.
The "Online tuning" function is active. A new calculation of the controller parameters is
performed cyclically if the estimated moment of inertia changes.
Effect
The speed controller gain is determined and set with the aid of a noise signal.
"Function is being prepared"
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.
"Function is being prepared"
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.
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.
