12 CONTROL SUB FUNCTIONS
12.7.7 Acceleration/deceleration processing function
The "acceleration/deceleration processing function" adjusts the
acceleration/deceleration when each control is executed.
Adjusting the acceleration/deceleration processing to match the control enables more
precise control to be carried out.
There are two acceleration/deceleration adjustment items that can be set:
"Acceleration/deceleration time 0 to 3", and "acceleration/deceleration method setting".

In the QD75MH, 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 QD75MH.
The set details are validated when written to the QD75MH.
