Siemens 14300 - Block overlaid handwheel motion activated incorrectly

Block overlaid handwheel motion activated incorrectly

Handwheel override has been called up incorrectly: - 1st For positioning axes: - Handwheel override programmed for indexing axes, - No position programmed, - FA and FDA programmed for the same axis in the block. - 2nd For contouring axes: - No position programmed, - G60 not active, - 1st G group incorrect (only G01 to CIP) Control reaction: Correction block is reorganized. Interface signals are set. Alarm display.

Root Cause Summary

Alarm 14300 occurs when the SINUMERIK tool management system cannot locate a valid tool record in the TM database for the requested T-function call. The controller requires complete tool geometry data including length and radius compensation values to execute the toolpath safely.

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.

Causes and Fixes

  1. 1

    Access Tool Management

    Press MENU SELECT → Machine → Tool Management or use softkey 'TOOL MANAGEMENT' from main screen.

    Use F4 'Magazine' view to see all available tool slots and their status

  2. 2

    Create new tool record

    Select empty T-number slot, press 'NEW TOOL' softkey, enter tool type (drill, mill, etc.) and assign the required T-number matching your NC program.

    Ensure tool number matches exactly with NC program T-call

  3. 3

    Define tool geometry

    Enter tool length compensation in 'Length 1' field and radius compensation in 'Radius' field. Set tool type parameters and cutting edge data.

    Use 'MEASURE' function if available to automatically capture tool dimensions

  4. 4

    Activate tool record

    Press 'ACTIVATE' softkey to write tool data to controller memory and make it available for NC program execution.

DIY Feasiblehigh confidence

Call a technician if:

  • ·TM database corruption persists after reorganization
  • ·Magazine synchronization hardware issues
  • ·Parameter access restrictions due to protection level

Prevention

  • Maintain standardized tool naming conventions
  • Regular TM database backups
  • Verify tool data completeness during setup
  • Use tool presetting systems for accurate geometry data

Common Mistakes

  • Forgetting to activate tool records after creation
  • Case-sensitive tool name mismatches
  • Assuming zero compensation values are invalid
  • Not checking magazine synchronization after tool changes
