What causes Siemens SINUMERIK alarm 14154?

Fine correction value in parameter %3 exceeds the limit defined in $MC_TOCARR_FINE_LIM_LIN (linear) or $MC_TOCARR_FINE_LIM_ROT (rotary). Incorrect tool offset or fine correction data programmed in the part program for orientable toolholder. Machine data limits $MC_TOCARR_FINE_LIM_LIN or $MC_TOCARR_FINE_LIM_ROT set too restrictively. Tool compensation table contains out-of-range fine correction values. $SC_TOCARR_FINE_CORRECTION setting data not properly configured or disabled.

How do I fix Siemens SINUMERIK alarm 14154?

1. Verify the fine correction value in parameter %3 of block %2 against current machine data limits in $MC_TOCARR_FINE_LIM_LIN and $MC_TOCARR_FINE_LIM_ROT using Diagnostics menu 2. Review the part program block %2 in channel %1 and reduce fine correction values to comply with machine data limits, or adjust limits if within machine capability 3. Check tool offset table and ensure all fine correction entries for orientable toolholders are within permissible ranges 4. Confirm $SC_TOCARR_FINE_CORRECTION setting data is enabled and properly configured for the toolholder type being used 5. Reset tool compensation data and re-enter fine corrections within validated limits, then restart the affected block

Alarm 14154

Siemens 840D 14154 - Channel block The amount of fine correction in parameter

The maximum permissible value of the fine correction in an orientable toolholder is limited by the machine data $MC_TOCARR_FINE_LIM_LIN for linear variables, and by the machine data $MC_TOCARR_FINE_LIM_ROT for rotary variables. The alarm can only occur if the setting data $SC_TOCARR_FINE_CORRECTION

Common Causes

Fine correction value in parameter %3 exceeds the limit defined in $MC_TOCARR_FINE_LIM_LIN (linear) or $MC_TOCARR_FINE_LIM_ROT (rotary)
Incorrect tool offset or fine correction data programmed in the part program for orientable toolholder
Machine data limits $MC_TOCARR_FINE_LIM_LIN or $MC_TOCARR_FINE_LIM_ROT set too restrictively
Tool compensation table contains out-of-range fine correction values
$SC_TOCARR_FINE_CORRECTION setting data not properly configured or disabled

Troubleshooting Steps

1Verify the fine correction value in parameter %3 of block %2 against current machine data limits in $MC_TOCARR_FINE_LIM_LIN and $MC_TOCARR_FINE_LIM_ROT using Diagnostics menu
2Review the part program block %2 in channel %1 and reduce fine correction values to comply with machine data limits, or adjust limits if within machine capability
3Check tool offset table and ensure all fine correction entries for orientable toolholders are within permissible ranges
4Confirm $SC_TOCARR_FINE_CORRECTION setting data is enabled and properly configured for the toolholder type being used
5Reset tool compensation data and re-enter fine corrections within validated limits, then restart the affected block
