14.13 Automatic Error Detection

14.13.1 Outline

The cutting at corner area (the continuous blocks with different movement directions) may have rounding because of
acceleration/deceleration or servo response delay. Turning ON the error detection increases the edge accuracy; however, the
cycle time will be longer as the deceleration check is performed in every cutting block.
Using this function, the timing for starting the next cutting block is controlled (waited) until the amount of position error at the
corner area becomes equal to or less than the parameter value in order to cut edges with high accuracy. The timing for
starting the next block is controlled when the result of corner angle calculation is smaller than the parameter value, and it is
not controlled when the result of corner angle calculation is larger than the parameter value. The basis whether the result
value is large or not can be set by the parameter.
Using this function, the high-accurate edge cutting can be performed without too much extending the cycle time.
When the error detection is OFF, the
next movement will be started without
waiting for the deceleration.
When the automatic error detection is
ON, the next movement will be started
judging the corner angle and waiting
until the position error amount becomes
the designated value or less.
