Asymmetric Linear Acceleration/Deceleration with Constant
Acceleration/Deceleration
With asymmetric linear acceleration/deceleration, the linear acceleration/deceleration
described in , is used, but separate rates can be set for acceleration and deceleration.
For deceleration, for example, the time T required to stop from the Speed set in parameter
Pn821 in a positioning operation can be calculated using the following formula.
T [ms] = Pn823 × (Pn821/Pn843)
If this acceleration/deceleration pattern is used, the rates of acceleration/deceleration will
remain constant even if the Speed set in Pn821 is changed.
