Optimum Torque acceleration/deceleration (M Series)
General
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 and
performs linear type positioning with optimum acceleration/deceleration during AI high
precision contour control mode or AI nano high precision contour control mode.
Usually, because of the friction of the machine, gravity, the torque characteristics of the
motor, and other factors, the acceleration/deceleration performance (torque for
acceleration/deceleration) is different with direction of movement, acceleration or
deceleration. In this function, acceleration pattern of rapid traverse for the following
situations, plus movement and acceleration, plus movement and deceleration, minus
movement and acceleration, minus movement and deceleration can be set into parameters
according to the torque for acceleration/deceleration of each situation.
Acceleration/deceleration can be performed according to these parameter setting, so that the
most of the capability of the motor can be used and positioning time can be reduced.
