Precision This sets the compensation coefficient of the control
coefficien error during the high-accuracy mode.
The compensation coefficient is set when further
reducing the control error of the roundness and arc
radius reduction amount at the corner.
The maximum control error is displayed in ( ).
Theoretically, the accuracy error becomes smaller
as the setting value becomes larger, but because the
speed and arc clamp speed at the corner become
lower, the cycle time becomes longer.
Corner slow In the high-accuracy mode, this automatically judges
angle the corner, and realizes a smooth, curved line or a
sharp corner.
In the high-accuracy control mode, when the angle
(exterior angle) between blocks is larger than the
setting value, it is judged as a corner. The machine
will decelerate to make the edge. Consequently, set
the minimum value to be recognized as an angle
(exterior angle).
Arc speed During high-accuracy control, this sets whether the
ctrl valid speed control is valid or invalid at the arc entrance
and exit.
Arc During high-accuracy control, this sets the
slowdown deceleration speed when the speed control is valid at
speed the arc entrance and exit.
