Supplement to Manual
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.

Fig.1 The acc./dec. time constant type bell-shaped acc./dec. after rapid traverse interpolation
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.
