Acceleration/deceleration time change function
Acceleration/deceleration time change function is used to change the acceleration/deceleration time during the speed change
to an arbitrary value when the speed change is performed using 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 (values in [Pr.9], [Pr.10], and [Pr.25] to [Pr.30]) is set in [Da.3] and [Da.4] of the positioning
data, and the control is performed with that acceleration/deceleration time. However, by setting a new acceleration/
deceleration time ([Cd.10] and [Cd.11]) to 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] and [Cd.11]).
Control details
After setting the following two items, perform the speed change to change the acceleration/deceleration time at the speed
change.
• Setting a new value of the acceleration/deceleration time ([Cd.10] New acceleration time value, [Cd.11] New deceleration
time value)
• Enabling the acceleration/deceleration time change ([Cd.12] Acceleration/deceleration time change during speed change,
enable/disable selection)
The following figure shows the operation at the acceleration/deceleration time change.
