Alarm 10742

Siemens 10742 - Block WAB distance invalid or not programmed

Possible causes: In a WAB block, the parameter DISR has not been specified or its value is less than or equal to 0. During approach or retraction with circle and active tool radius, the radius of the internally generated - WAB contour is negative. The internally generated WAB contour is a circle with a radius which, when offset with the current offset radius (sum of tool radius and offset value OFFN), yields the tool center point path with the programmed radius DISR Control reaction: Correction block is reorganized. Local alarm reaction. Interface signals are set. Alarm display. NC Stop on alarm at block end.

Safety

  • Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.

Common Causes

  • Possible causes: In a WAB block, the parameter DISR has not been specified or its value is less than or equal to 0.
  • During approach or retraction with circle and active tool radius, the radius of the internally generated - WAB contour is negative.
  • The internally generated WAB contour is a circle with a radius which, when offset with the current offset radius (sum of tool radius and offset value OFFN), yields the tool center point path with the programmed radius DISR

Troubleshooting Steps

  1. 1Modify part program.
  2. 2Clear alarm with NC START or RESET key and continue the program
