High-Accuracy Control

In high-accuracy control, the deviation in work that is caused by the delay in the control system is controlled. High-accuracy
control is effective in work that requires sharp edges at corners and work that requires the deviation on curves to be
minimized. By pre-reading several blocks ahead, acceleration/deceleration that does not cause deviations in work can be
applied, and deceleration control that suits the workpiece shape is automatically applied so that extended working time is kept
to a minimum while controlling deviations in work.

The following functions are available in high-accuracy control mode.
• Acceleration/deceleration before interpolation (Page 226 Acceleration/deceleration before interpolation)
• Optimum speed control (Page 228 Optimum speed control)
• Vector accuracy interpolation (Page 234 Vector accuracy interpolation)
• Arc entrance/exit speed control (Page 234 Arc entrance/exit speed control)
During high-accuracy control mode, do not command a block with no movement as an independent block.
When a block with no movement is commanded as an independent block, the switching of blocks can take
time.
