Siemens 840D 61002 - Channel block: Type of machining incorrectly defined

Channel block: Type of machining incorrectly defined

The value of the VARI parameter for the machining has been incorrectly specified. Alarm triggered by following cycles: SLOT1, SLOT2, POCKET1 to POCKET4, CYCLE71, CYCLE72, CYCLE76, CYCLE77, CYCLE93, CYCLE95, CYCLE97, CYCLE98. Remedy: Modify VARI parameter.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • VARI parameter assigned an invalid or out-of-range numerical value
  • VARI parameter type mismatch (integer expected vs. string or decimal provided)
  • Incompatible VARI value for the selected machining cycle (e.g., SLOT1, POCKET3)
  • VARI parameter not initialized before cycle call
  • Incorrect syntax or missing VARI assignment in part program

Troubleshooting Steps

  1. 1Review the part program block triggering the alarm and identify which cycle (SLOT1, SLOT2, POCKET1-4, CYCLE71, CYCLE72, CYCLE76, CYCLE77, CYCLE93, CYCLE95, CYCLE97, CYCLE98) is active
  2. 2Check the VARI parameter value currently defined in the program against the cycle documentation to verify it is within the acceptable range for that specific machining type
  3. 3Confirm VARI parameter is declared as an integer type and is assigned before the cycle is called
  4. 4Consult the Siemens 840D/828D cycle reference manual for the specific cycle to determine valid VARI values and their meanings
  5. 5Correct the VARI parameter assignment in the source code, save, and recompile the part program before restarting
