Appendix B
Estimating Times and Pulses for
Acceleration/Deceleration
If the acceleration/deceleration time designation parameter in the axis parameter area is set to 0, the accelera-
tion time will be the time required to go from the initial speed set in the axis parameter area to the maximum
speed and the deceleration time will be the time required to go from the maximum speed to the initial speed. If
the acceleration/deceleration time designation parameter in the axis parameter area is set to 1, the accelera-
tion and deceleration times will be the times required to go from the present speed to the target speed. Accord-
ingly, when the acceleration/deceleration time designation parameter in the axis parameter area is set to 0, the
time it takes to reach the target speed, the time from the target speed to the initial speed, as well as the number
of pulses for each of them, can all be found by means of the formulas shown below.
