Alarm 61258 occurs when the F_SUB_SP cycle attempts to execute counterspindle chuck operations, but the required spindle parameters for the counterspindle have not been configured in the spindle data view. This is a configuration validation error in the NCK that prevents the cycle from initializing proper counterspindle chuck control.

Root Cause Summary

Alarm 61258 occurs when the F_SUB_SP cycle attempts to execute counterspindle chuck operations, but the required spindle parameters for the counterspindle have not been configured in the spindle data view. This is a configuration validation error in the NCK that prevents the cycle from initializing proper counterspindle chuck control.

Causes and Fixes

1
Navigate to Diagnostics > Parameters > Spindle View in the SINUMERIK control UI. Verify that a spindle entry exists for the counterspindle (typically spindle index 2 or higher if spindle 1 is main spindle).
Do not confuse the spindle view with general machine data. The spindle view is spindle-specific configuration.
2
Check SD 32300 (SPIND_TYPE) is set to 2 (counterspindle) and SD 32110 (MAX_SPIND_SPEED) contains a valid maximum RPM value. Verify SD 32400 (SPIND_CTRL_TYPE) is configured appropriately for chuck control.
3
Confirm MD 20050 (number of spindles) matches the actual spindle count and that the counterspindle is assigned to a valid spindle index within this count.
4
Save all parameter changes, perform a cold start (POWER OFF > POWER ON), and retry the F_SUB_SP cycle.
