In Figs. 2 and 3:
Ts = Cutting feed acceleration/deceleration time constant
Lc = In-position width
As shown in Fig. 3, the remaining distance (shaded area in Fig. 3) of the previous block when
the next block is started can be set into the servo parameter "#2224 SV024" as the in-position
width "Lc".
The in-position width is designed to reduce the roundness at the workpiece corners to below
the constant value.

To eliminate corner roundness, set the value as small as possible to servo parameter "#2224
SV024" and perform an in-position check or assign the dwell command (G04) between blocks.
