This function is designed to enable high–speed, high–precision axis
operation. With this function, delay due to acceleration/deceleration and
delay in the servo system that increase with an increasing feedrate can be
suppressed.
This function allows the tool to trace a specified value precisely, thus
leading to a minimum path error.
This function is enabled when the advanced preview feed–forward
control mode is set. For details, refer to the relevant manual issued by the
machine tool builder.
