What causes Siemens SINUMERIK alarm 22013?

Programming error in the part program related to the spindle function. Spindle configuration parameter mismatch for the commanded operation. Spindle encoder signal fault preventing speed or position control. Spindle drive fault affecting the ability to execute the commanded function. Gear stage or spindle mode conflict with the commanded function.

How do I fix Siemens SINUMERIK alarm 22013?

1. Review the program block that triggered the alarm for spindle command errors. 2. Check the SINAMICS spindle drive diagnostics for fault codes. 3. Verify spindle encoder signal quality in the diagnostics screen. 4. Review spindle configuration parameters for the commanded gear stage and mode. 5. Consult the Siemens SINUMERIK alarm manual for alarm 22013 specific remedy.

Alarm 22013

Siemens 840D 22013 - Channel block dependent spindle is in simulation.

Alarm 22013 occurs when a dependent spindle/axis designated for synchronous coupling is operating in simulation mode while its lead spindle/axis is in normal (non-simulation) mode. The SINUMERIK 840D NCK cannot establish spindle synchronism because the dependent spindle's actual motion feedback is suppressed by simulation, preventing real-time coupling control.

Root Cause Summary

Alarm 22013 occurs when a dependent spindle/axis designated for synchronous coupling is operating in simulation mode while its lead spindle/axis is in normal (non-simulation) mode. The SINUMERIK 840D NCK cannot establish spindle synchronism because the dependent spindle's actual motion feedback is suppressed by simulation, preventing real-time coupling control.

Causes and Fixes

1
Access Siemens HMI > Diagnostics > Machine Data > filter for spindle number. Locate MD20090 for the dependent spindle (indicated by %3 in alarm message).
2
Verify MD20090 value: 0 = normal operation, 1 = simulation. Compare with lead spindle's MD20090 setting—both must match (typically both = 0 for production coupling).
Do not set dependent spindle MD20090 = 0 until hardware initialization and encoder calibration are complete.
3
If dependent spindle must remain in simulation for testing, set lead spindle MD20090 = 1 to match. Otherwise, set dependent spindle MD20090 = 0 to enable real coupling.
