7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL

NOTE
If the error detect signal is on, a cutting block is not executed
until the acceleration/deceleration of the previous cutting
block has been completed.
This function alone cannot prevent corner rounding due to
delay caused by the servo motor, however.
To prevent corner rounding due to delay caused by the
servo motor, use the in–position check function together
with this function.

Feed–forward control can be performed even during rapid traverse. In
this case, the servo position error is reduced, thus reducing the time
required for positioning to within the specified range.
