Default settings for the sampling times

The sampling times of the functions are pre-assigned automatically when the drive is
configured.
These default settings are based on the selected mode (vector/servo control) and the activated
functions.
If isochronous mode is to be possible with a controller, before the automatic configuration,
parameter p0092 must be set to "1" in order that the sampling times are appropriately preset.
If isochronous operation is not possible due to incorrect sampling time settings, an appropriate
message will be output (A01223, A01224).
If the application requires a change of the preset sampling times, they can be set using
parameters p0112 and p0113 or directly using p0115, p0799 and p4099.
Note
Recommendation
Only appropriately qualified experts should change the sampling times set as default values.
When commissioning for the first time, the current controller sampling times (p0115[0]) are
automatically preset with factory setting values:
