When the non–linear interpolation type is selected, movement is
performed at the feedrate set in parameter No. 1420 with
acceleration/deceleration set in parameter No. 1620. The corresponding
value can be set in parameter No. 1621 to select bell–shaped
acceleration/deceleration.
NOTE
Rapid traverse block overlap is disabled.
