Continuous-Path Mode, Exact Stop, LookAhead (B1)

Scope of the path criterion
• ADIS or ADISPOS must be programmed. If the default is "zero", G641 behaves like G64.
• If only one of the blocks involved is rapid traverse G00, the smaller rounding distance
applies.
• If a very small value is used for ADIS, the control must make sure that every interpolated
block, even an intermediate rounding block, contains at least one interpolation point. The
maximum path velocity is thereby limited to ADIS/interpolation cycle.
• Irrespective of ADIS and ADISPOS, the rounding area is limited by the block length.

In blocks with short distances (distance < 4*ADIS and < 4 * ADISPOS respectively), the
rounding distance is reduced so that a traversable part of the original block is retained. The
remaining length depends on the axis path and is approximately 60% of the distance still to
be traversed in the block.
