Acceleration/Deceleration Time Change Function - Mitsubishi Electric QD77MS User Manual

13.5.3 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 value during speed change,
enable/disable) 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".
