This function cannot be enabled for a single block or during dry run.
This function decelerates the feedrate when the difference between the
feedrates at the end point of block A and the start point of block B along
each axis is larger than the value specified in parameter No. 1781. The
function executes block B when the feedrates along all axes are smaller
than the feedrate specified in parameter No. 1741. In this case, the
function determines that the number of accumulated pulses is zero.
The flowchart for feedrate control is shown below.
