2.2 List of parameters
SINAMICS G120C
240 List Manual (LH13), 04/2014, A5E33840768B AA
Description: Setting the functions for online tuning (p5300 = 2).
As long as autotuning is still active (p5300 <> 0), it is not possible to change the configuration.
A noise signal is required for some measuring steps.
Dependency: This parameter can only be changed if p5300=0 has been parameterized.
Refer to: p5300
Caution: Please note the general conditions of the moment of inertia estimator, online tuning and adaptive resonance filter.
See Function Manual FH1.
Note: Re bit 00: being prepared
The speed controller gain is determined and set using a noise signal.
Re bit 01: being prepared
Possibly required current setpoint filters are determined and set using a noise signal.
As a consequence, a higher dynamic performance can be achieved in the speed control loop.
Re bit 02:
Using this bit, the moment of inertia is determined while traversing (moment of inertia estimator). If this bit is not set,
then the load moment of inertia must be manually parameterized in parameter p1498.
Re bit 03:
If "once" has been parameterized, then after successfully determining the moment of inertia p1498 the moment of
inertia estimator is deactivated.
If "Cyclic" has been parameterized, then the moment of inertia is continually determined and the controller
parameters adapted. After the moment of inertia has been successfully determined (r1407.26=1), we recommend
that the parameter is saved. This means that after power on, the controller does not have to re-stabilize.
Re bit 06:
The adaptation of a current setpoint filter can be set here. See p5280-p5285.
This adaptation may be necessary if a mechanical resonance frequency changes in operation. It can also be used to
dampen a fixed resonance frequency. Once the control loop has stabilized, this bit should be deactivated and the
determined parameters saved in a non-volatile fashion.
Re bit 07:
With this function, these axes are adapted to the dynamic response set in p5275. This is necessary for interpolating
axes. The time in p5275 should be set according to the axis with the lowest dynamic response.
