(5) The neighborhood distance denotes the changing distance to the interpolation operation at the next tar-
get position. If this neighborhood distance (numerical value 1, numerical value 2) is omitted, the accel-
erate and deceleration starting position will be the changing position to the next interpolation. In this
case, it passes through a location away from the target position, but the operating time will be the short-
est. To pass through a location closer to the target position, set this neighborhood distance (numerical
value 1, numerical value 2).
If the MB and MC values
are different, connection
is m ade using a value
lower than the sm aller of
these two values.

(6) If the specifications of numerical value 1 and numerical value 2 are different, continuous operation will be
performed at the position (distance) that is the smaller of these two.
(7) If numeric value 2 is omitted, the same value as numeric value 1 will be applied.
(8) When continuous operation is specified, the positioning completion specification by the Fine command
will be invalid.
(9) If the proximity distance (value 1, value 2) is set small, the movement time may become longer than in
the status where Cnt 0.
(10) Even when continuous operation is specified, acceleration/deceleration is performed for the interpola-
tion instruction that specifies singular point passage as the interpolation method.
