Acceleration/deceleration processing function
The "acceleration/deceleration processing function" adjusts the acceleration/deceleration of each control to the acceleration/
deceleration curve suitable for device.
Setting the acceleration/deceleration time changes the slope of the acceleration/deceleration curve.
The following two methods can be selected for the acceleration/deceleration curve:
• Trapezoidal acceleration/deceleration
• S-curve acceleration/deceleration
Refer to the following for acceleration/deceleration processing of speed-torque control.
Page 193 Speed-torque Control
"Acceleration/deceleration time 0 to 3" control details and setting
In the Simple Motion module, four types each of acceleration time and deceleration time can be set. By using separate
acceleration/deceleration times, control can be carried out with different acceleration/deceleration times for positioning
control, JOG operation, home position return, etc.
Set the required values for the acceleration/deceleration time in the parameters shown in the following table, and write them to
the Simple Motion module.
The set details are validated when written to the Simple Motion module.
Refer to the following for the setting details.
Page 407 Basic Setting
"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. (except for inching operation, manual
pulse generator operation and speed-torque control.)
The two types of "acceleration/deceleration processing method" are shown below.
■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.
