14.13.4 Relation with Other Functions

 Milling mode
This function is disabled for a movement command which is in the milling mode.
 Tool compensation
For tool compensation or nose R compensation, the corner angle is calculated for the compensated block.
 Control axis synchronization (G125), control axis superimposition (G126), arbitrary axis exchange (G140, G141, and
G142), arbitrary axis superimposition (G156)
When control axis synchronization (G125), control axis superimposition (G126), arbitrary axis exchange (G140, G141,
G142), or arbitrary axis superimposition (G156) takes place in another part system, there may be delay in a block next to
cutting block of the part system to which the axes related to the said functions belong.
 Automatic machine lock
This function is disabled for an axis to which automatic machine lock is applied.
 High-accuracy control mode
The high-accuracy control enables machining with high corner-edge accuracy. Do not use this function during the high-
accuracy control mode.
 High-speed machining mode
This function is disabled during the high-speed machining mode.

14.13.5 Precautions

(1) As the comparison between the corner deceleration check width parameter and the position error amount is performed at
every constant time, the timing for starting the next block will be a little later than the set parameter value.
(2) This function is valid from a block next to the one where the automatic error detection signal is turned ON.
(3) When the angle of corner with a circular interpolation command is calculated, the tangential direction of the circular com-
mand's start or end point is treated as the travel direction.
(4) For the micro segment block with a high feedrate, the timing for starting the next block may be delayed.
(5) When the recalculation request ($1:YC2B to $8:Y14EB) is input with the PLC signal, the timing for starting the next block
is delayed.
