Outline
This function makes the acceleration/deceleration time constant, and makes the relationship
between feed rate and time of acceleration/deceleration bell-shape in the rapid traverse.
This function requires the following settings.
▪ The rapid traverse bell-shaped acceleration/deceleration. (optional function)
▪ The linear interpolation positioning. (parameter LRP(No.1401#1)=1)
▪ The acc./dec. time constant type acc./dec. (parameter RTC(No.1603#4)=1)
Explanation
The cutter path of the G00 command using this function is linear.
The relationship between feed rate and time at the acceleration as follows.

T1 is setting for each axis in parameter No.1620.
T2 is setting for each axis in parameter No.1621.
The acceleration/deceleration time is T1+T2.
When 0 is set to T1 or T2, the acceleration/deceleration type is linear.
When 0 is set to T1 and T2, the acceleration/deceleration does not execute.
If the time constants set for the axes differ from each other, proper straight lines cannot be
obtained.
