5. FEED FUNCTIONS
The flowchart for feedrate control is shown below.
Is the corner angle smaller than
the angle specified in parameter
Are the feedrates along the X–
and Y–axes smaller than that
specified in parameter No. 1741?
Further decelerates the
feedrate in block A
The number of accumulated
pulses is determined to be zero
and block B is executed
When the corner angle is smaller than the angle specified in the
parameter, the relationship between the feedrate and time is as shown
below. Although accumulated pulses equivalent to the hatched area
remain at time t, the next block is executed because the feedrate of the
automatic acceleration/deceleration circuit is smaller than the
parameter–set value. This function is effective only for movement on
the selected plane.
