4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Dry run invalid
[Function]
This signal disables dry run in dry run operation.
[Operation]
When the "Dry run invalid" signal (DRNC) is ON, the NC ignores the "Dry run" (DRN) function and operates at the
specified speed.
[Related signals]
(1) Dry run (DRN: YC15)
Cont. Signal name
A Automatic error detection
[Function]
With the "Automatic error detection" signal (AUTED), the timing for starting the next cutting block is controlled until the
amount of position error becomes equal to or less than the parameter value (corner deceleration check width), in order to
cut edges with high precision.
The timing for starting the next block is controlled when the result of corner angle calculation is smaller than the parameter
value (corner deceleration check angle).
[Operation]
The following operation is performed when the "Automatic error detection" signal (AUTED) is ON.
<Corner angle calculation control>
The timing for starting the next cutting block is controlled only when the corner angle θ (interior angle) calculated for
consecutive cutting blocks is equal to or smaller than the parameter value (corner deceleration check angle). The timing
for starting the next cutting block is not controlled when the corner angle is larger than the parameter value.
Angle calculation is performed for the plane axis selected with the plane selection command. Angle calculation is not
performed for the rotational axes.

<Start timing control>
Checking the amount of error is started after deceleration starts in the currently executed block. The next cutting block
starts when the amount of error (remaining distance after composition) between the machine position of the target axis
and the feedback machine position becomes equal to or less than the parameter value (corner deceleration check width).

Note
(1) Turn OFF the normally used "Error detection" signal (ERD) before using the "Automatic error detection" signal
(AUTED). When the "Error detection" signal (ERD) is ON, the normal error detection is given priority.
