Command format
G61.1 Ff1 ;
G61.1 : High-accuracy control mode

The high-accuracy control mode is validated from the block containing the G61.1 command.
G64

• G61 (exact stop check)
• G62 (automatic corner override)
• G63 (tapping mode)
• G64 (cutting mode)
Detailed description
(1) The "high-accuracy control" specifications are required to use this function.
If G61.1 is commanded when the specifications are not available, program error (P123) will
occur.
(2) The feedrate command F is clamped by the rapid traverse rate or maximum cutting feedrate
set with the parameters.
(3) Refer to the "Optimum speed control" mentioned later for details on the speed clamp during
an arc command.
(4) The own system waits for the other system to move and reach the designated start point, and
then starts.
(5) The modal holding state of the high-accuracy control mode depends on the conditions of the
base specification parameter "#1151 rstint" (reset initial) and "#1148 I_G611" (initial high-
accuracy).
