If the deceleration distance multiplication ratio is 4 times (pm2585 = 40), for example,
deceleration distance L’ is equivalent to the area of the shaded parts in Figs. 4.2.7.3 and
4.2.7.4. Fig. 4.2.7.3 shows how the feedrate changes when G01 blocks continue and Fig.
4.2.7.4 show the changes in feedrate when tool movement mode changes from the G01
mode to the G02 mode. Note that broken lines in Figs. 4.2.7.3 and 4.2.7.4 represent the
feedrate waveform including the delay due to “TS + Tp”.
