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".
