Example for experts: Axis tuning

Axis: User-defined strategy (108)
Manual setting of the measurement parameters
The tuning objective can be directly entered in "Speed" or "Position". Alternatively, a predefined
strategy (102, etc.) can be selected, accepted with "Adapt strategy" and then changes can be
made.
By activating the checkbox, the commissioning engineer selects the individual steps for
measuring and tuning. Several steps are interdependent: For instance, the speed-controlled
system must always be measured before tuning the speed controller. All checkboxes which
result in a measurement are marked with an arrow. Additional default settings are available for
each measurement using the "Meas. parameters >" vertical softkey.
Perform preliminary measurement to determine the excitation:
The preliminary measurement to determine the excitation can always be selected or
deselected. The preliminary measurement is always recommended when first commissioning
the axis or for unknown mass relationships (load/motor). The measurement parameters for the
following measurement are automatically determined after the preliminary measurement. User-
defined measurement parameters are then overwritten.
