D Neural QEC parameterization
You can select the menu with the function parameters for the neural QEC func-
tion with this softkey.
Fig. 9.31
Notes You enter the function parameters in this display. If the neural QEC has not yet
been started up for this axis, all parameters are set to 0. Meaningful standard
parameter settings can be assigned by means of the file functions with “Load file:
STANDD_Q”. The current parameter settings are displayed if a data block is al-
ready stored in the boot file or if the neuronal network has been activated since
the last power ON for the axis displayed.

)
settings This parameter defines the upper limit of the operating range. Values of > 0
may be entered. The default setting after “Load default” is 500 mm/s
2 .
S
Lower range limit (a1)
This parameter defines the limit of the lower acceleration range. Values of >0
and <100 may be entered. The default setting after “Load default” is 2 %.
S
Medium range limit (a2)
This parameter defines the limit of the medium acceleration range. Values of
>0 and <100 may be entered. The default setting after “Load default” is 60 %.
S
Direction dependence
This parameter determines the direction-specific compensation. The states
“yes” or “no” may be selected. The default setting after “Load default” is “no”.
S
Fine quantization
This parameter defines the fine quantization of the input quantity. Values of
