*1 The software stroke limit check is carried out for the following addresses during circular interpolation control.
(Note that "[Da.7] Arc address" is carried out only for circular interpolation control with sub point designation.)
Current value/end point address ([Da.6])/arc address ([Da.7])
• If an error is detected during continuous path control, the axis stops immediately on completion of execution of the
positioning data located right before the positioning data in error.
Ex.
If the positioning address of positioning data No. 13 is outside the software stroke limit range, the operation immediately stops
after positioning data No. 12 has been executed.
