7-7 Acceleration/Deceleration Operation
CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
Calculation of Basic Acceleration/Deceleration Time
The operation time based on the acceleration time and deceleration time which you specified
in the sequence data, is determined by the axis parameter [Acceleration/Deceleration Time
Selection].
Similarly, the operation time based on the interpolated acceleration time and interpolated
deceleration time is determined by the sequence data [Interpolation Acceleration/Deceleration
Time Selection].
If you specify [0: Acceleration/deceleration specified] under [Acceleration/Deceleration Time
Selection] or [Interpolation Acceleration Time Selection], the time to reach [Maximum Speed]
from [Starting Speed] is the acceleration time, while the time to reach [Starting Speed] from
[Maximum Speed] is the deceleration time.
If you specify [1: Time specified], the acceleration time and deceleration time are the time
needed to reach the target speed from the present speed.
This section explains the acceleration time and deceleration time when you specify [0:
Acceleration/deceleration specified] under [Acceleration/Deceleration Time Selection] or
[Interpolation Acceleration/Deceleration Time Selection].
Acceleration time T1 and deceleration time T2 are determined by the formulas below:
Maximum speed specified
Acceleration time T1 = (V1 − V0) / (Vmax − V0) × Ta
Deceleration time T2 = (V1 − V0) / (Vmax − V0) × Td
