When the spindle has the gear change mechanism, please refer to our
recommended gear change sequence for smooth gear change. In our
recommended sequence, this parameter is used.

This parameter is used for the position gain polygonal line function in the
position coder method spindle orientation.
This function doubles the position gain in low speed range.
