5.4.3 Optimum Torque Acceleration/Deceleration
This function enables acceleration/deceleration in accordance with the
torque characteristics of the motor and the characteristics of the
machines due to its friction and gravity. Usually, because of the friction
and gravity of the machine, the torque characteristics of the motor, and
other factors, the acceleration/deceleration performance that is attainable
(referred to as the limited acceleration/deceleration curve) is not
symmetrical with respect to the line separating the low- and high-speed
portions. This function enables acceleration/deceleration in such a way
that in positioning, the actual acceleration curve follows the limited
acceleration curve as closely as possible. This makes the most of the
capability of the motor, reducing positioning time.
By setting limited acceleration curve data for each axis using the
appropriate parameter, this function performs linear type positioning
with acceleration/deceleration on the basis of limited acceleration curve
data in the state in which look-ahead acceleration/deceleration is
effective.
