The tolerance means a distance between a curve-C and a line-L.

7677 Minimum tolerance of a block executed with smooth interpolation
[Input type] Setting input
[Data type] Real
[Unit of data] mm, inch (input unit)
[Minimum unit of data] Depend on the increment system of the reference axis
[Valid data range] 9 digit of minimum unit of data (refer to standard parameter setting
table (A) )
(When the increment system is IS-B, -999999.999 - +999999.999)
Set the tolerance to be checked as a condition for performing smooth
interpolation. When the tolerance specified in a block is smaller than
this setting, the block is executed without smooth interpolation.
Normally, set a value near one-tenth of the maximum tolerance
(parameter No. 7676) . When a value of 0.0 is set, the minimum
tolerance is assumed to be one-tenth of the maximum tolerance
(parameter No. 7676) . When a negative value is set, the minimum
tolerance is assumed to be 0.0.
7681 Sequence number for stoppage upon matching
[Input type] Setting input
[Data type] Integer
[Valid data range] 1 - 99999999
When the sequence number set in this parameter appears during
program execution, single block stop state is set after the block is
executed. In this case or in the case of a reset, this parameter is
cleared to 0.
NOTE
1 When 0 is set, stoppage upon matching is disabled.
This means that even when there is a block of N0,
single block stop state does not occur with the block.
2 If a match is found with the sequence number of a
block processed internally within the CNC only (such
as a macro statement, M98, or M99), stoppage upon
matching is not performed.
3 If a match is found with the sequence number of a
block that specifies the number of repeats (such as L
specification in a canned cycle), operation stops
after the specified number of repeats are performed.
