Parameters: %1 = Channel number %2 = Block number, label Definitions: In a WAB retraction block with quar ter circle or semi-circle (G248 or G348), the end point in the machining plane was not programmed, and either G143 or G140 without tool ra dius compensation is active. Reaction: Correction block is reorganized. Local alarm reaction. Interface signals are set. Alarm display. NC Stop on alarm at block end. Remedy: Modify part program. The fo llowing changes are possible: - Indicate end point in the machining plane in the WAB block. - Activate tool radius compensation (effective for G140 only, not for G143). - State retraction side explicitly with G141 or G142. - Perform retraction with a straight line instead of a circle.
