Estimating Times and Pulses for
Acceleration/Deceleration
If 0 is set for the acceleration/deceleration time designation in an axis parameter area, the acceleration time is
the time it takes to reach the maximum speed from the initial speed (which is also set in the axis parameter
area). The deceleration time is the time from the maximum speed to the initial speed. If 1 is set for the acceler-
ation/deceleration time designation, the acceleration or deceleration time is directly set as the time from the
present speed to the target speed.
The time it takes to the reach the target speed, the time from the target speed to the initial speed, and the num-
ber of pulses for each of them can all be found by means of the formulas shown below when 0 is set for the
acceleration/deceleration time designation.
V
M
: Maximum speed setting
T

T

: Deceleration time from target speed (V

: Deceleration time setting
Using the above abbreviations, the number of pulses for the acceleration and deceleration time can be calcu-
lated as follows:
