[2]"Acceleration/deceleration method setting" control details and setting

In the "acceleration/deceleration method setting", the acceleration/deceleration processing method is selected and set. The set acceleration/deceleration processing is applied to all acceleration/deceleration.

The two types of "acceleration/deceleration method setting" are shown below.

(1)Automatic trapezoidal acceleration/deceleration processing method

This is a method in which linear acceleration/deceleration is carried out based on the acceleration time, deceleration time, and speed limit value set by the user.

Time

Fig. 12.45 Automatic trapezoidal acceleration/deceleration processing method

(2) S-pattern acceleration/deceleration processing method

In this method, the motor burden is reduced during starting and stopping. This is a method in which acceleration/deceleration is carried out gradually, based on the acceleration time, deceleration time, speed limit value, and " Pr.35 S-pattern proportion" (1 to 100%) set by the user.

When the stepping motor is used, the S-pattern acceleration/deceleration processing method cannot be carried out. When using this processing method, ensure to use a servomotor.
