For example, in the case of parts programs generated by means of CAD sys-
tem, which contain extremely short blocks, this limiting of the path velocity can
result in a strong reduction of the path velocity over several parts program
blocks.
The function “Online compressor” can help to avoid such sudden velocity dips.
