12 CONTROL SUB FUNCTIONS
12.5.3 Acceleration/deceleration time change function
The "acceleration/deceleration time change function" is used to change the
acceleration/deceleration time during a speed change to a random value when
carrying out the speed change by the "speed change function" and "override function".
In a normal speed change (when the acceleration/deceleration time is not changed),
the acceleration/deceleration time previously set in the parameters ( Pr.9 , Pr.10 ,
and Pr.25 to Pr.30 values) is set in the positioning parameter data
items Da.3 and Da.4 , and control is carried out with that acceleration/deceleration
time. However, by setting the new acceleration/deceleration time ( Cd.10 , Cd.11 ) in
the control data, and issuing an acceleration/deceleration time change enable
command ( Cd.12 Acceleration/deceleration time change during speed change,
enable/disable selection) to change the speed when the acceleration/deceleration time
change is enabled, the speed will be changed with the new acceleration/deceleration
time ( Cd.10 , Cd.11 ).
The details shown below explain about the "acceleration/deceleration time change
function".
