Calculation of Acceleration/Deceleration Time in Continuous Positioning
The example below assumes that the completion pattern of sequence data is continuous 1.
It shows as an example, calculation formulas for acceleration time and deceleration time based
on execution of sequence No. 0 to 2.
Acceleration time T1 = (V1 − V0) / (Vmax − V0) × Ta1
Acceleration time T2 = (V2 − V1) / (Vmax − V0) × Ta1
Deceleration time T3 = (V2 − V3) / (Vmax − V0) × Td2
Deceleration time T4 = (V3 − V0) / (Vmax − V0) × Td3
In the case of continuous 1, use the acceleration time or deceleration time under the present
sequence data until the sequence data changes to the next one, as shown by the above
calculation formulas.
If the speed under the next sequence data to be executed is higher than the present speed,
use the acceleration time. If the speed under the next sequence data to be executed is lower
than the present speed, use the deceleration time.
