Refer to Section 5.2 "List of parameters" for setting details.
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".
The details shown below explain about the "acceleration/deceleration processing
function".
[1] "Acceleration/deceleration time 0 to 3" control details and setting
[2] "Acceleration/deceleration method setting" control details and setting
[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.
Setting
value
Set the acceleration time at a value within the range
of 1 to 8388608 ms.
Set the deceleration time at a value within the range
of 1 to 8388608 ms.
