When the G00 pre-interpolation acceleration/deceleration and the soft acceleration/deceleration
are used together, the inclination of soft acceleration/deceleration will be steeper by setting a
time to the soft acceleration/deceleration 2nd step time constant (#2005 G0t1).
Consequently, the acceleration for G28/G30 will be larger than that for G00.
(1) Total accelerating time is "G0tL".
(2) The time for curve part is "G0t1".
(3) The time for linear part is obtained by "G0tL-(2 x G0t1)".

When the G00 pre-interpolation acceleration/deceleration and the soft acceleration/deceleration
are used together, you can attain the G28/G30 acceleration that is equal to G00, by setting the
same value to G00 soft acceleration/deceleration filter (#1569 SfiltG0) as well as to the soft
acceleration/deceleration 2nd step time constant (#2005 G0t1).
(1) Total accelerating time is obtained by "G0tL+G0t1".
(2) The time for curve part is "G0t1".
(3) The time for linear part is obtained by "G0tL-G0t1".
