12 CONTROL SUB FUNCTIONS
12.7.6 Acceleration/deceleration processing function
The "acceleration/deceleration processing function" adjusts the
acceleration/deceleration of each control to the acceleration/deceleration curve
suitable for devices.
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
The details shown below explain about the "acceleration/deceleration processing
function".

[1] "Acceleration/deceleration time 0 to 3" control details and setting
In the QD75, 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, OPR, etc.
Set the required values for the acceleration/deceleration time in the parameters
shown in the following table, and write them to the QD75.
The set details are validated when written to the QD75.
