2.24 Optimum Torque Acceleration/Deceleration
2.24.1 Outline
This function is an additional option.
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 HPCC / AI NANO HPCC 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.
