What causes Siemens SINUMERIK alarm 104032?

Required machine data or parameter not configured for the requested function. Option bit not set in SINUMERIK to enable the required functionality. Program references a function or axis that has not been configured. Machine commissioning incomplete — required setup step was not performed. Configuration data cleared or lost due to a parameter reset or hardware change.

How do I fix Siemens SINUMERIK alarm 104032?

1. Read the full alarm message to identify what is missing (axis name, parameter number, function name). 2. Consult the SINUMERIK alarm manual for alarm 104032 for the specific configuration requirement. 3. Check the relevant machine data group and set the required parameter. 4. If a specific option is required, verify it is licensed and enabled in the SINUMERIK option settings. 5. Power cycle after making configuration changes to apply the new settings.

Alarm 104032

Siemens 840D 104032 - There is no preselected cutting edge

Alarm 104032 occurs when the control system attempts to execute a machining operation but cannot find a valid cutting edge preselection for the active tool. This typically happens when using tools with multiple cutting edges (indexed tools, turret tools) where the specific cutting edge must be defined before machining begins, but no valid preselection exists in the program or tool data.

Causes and Fixes

1
Review the NC program at the line where the alarm occurred and locate the tool call (T command).
2
Verify that a D-number (cutting edge number) is specified in the program, such as 'T1 D1' where D1 selects cutting edge 1.
3
Check if the tool requires multiple cutting edges by reviewing tool data - verify $TC_DP1[tool,edge] (tool type) indicates an indexed or turret tool.
4
Add or correct the D-number in the tool call command (e.g., change 'T5' to 'T5 D1') and restart the program.
Ensure the D-number corresponds to an existing cutting edge defined in the tool management system.
