What causes Siemens SINUMERIK alarm 310709?

SINAMICS drive hardware fault requiring investigation. Drive parameter configuration error. Axis motor or feedback system fault triggering drive protection. Communication fault on the drive bus. Power supply issue affecting the drive module.

How do I fix Siemens SINUMERIK alarm 310709?

1. Check the SINAMICS drive for active fault codes in the diagnostics screen. 2. Power cycle the machine to clear transient faults. 3. Review SINAMICS parameters for the affected drive axis. 4. Check the SINUMERIK axis diagnostics for related NC alarms. 5. Consult the Siemens SINAMICS alarm manual for alarm 310709 complete remedy.

Alarm 310709

Siemens 840D 310709 - Axis drive error in piston diameter or piston rod diameter

This alarm occurs when the piston diameter or piston rod diameter values in the drive machine data (MD 5131, MD 5132, MD 5133) are invalid, such as a piston diameter less than or equal to zero or a rod diameter exceeding the piston diameter. Correct the values in the respective MD parameters to resolve.

Axis drive error in piston diameter or piston rod diameter

Root Cause Summary

This alarm occurs when the piston diameter or piston rod diameter values in the drive machine data (MD 5131, MD 5132, MD 5133) are invalid, such as a piston diameter less than or equal to zero or a rod diameter exceeding the piston diameter. Correct the values in the respective MD parameters to resolve.

Safety

Refer to Siemens documentation
Ensure qualified technician performs repairs

Causes and Fixes

1
Access machine data
Navigate to the drive parameters in the Siemens control under MD 5131, MD 5132, and MD 5133.
2
Verify and correct values
Ensure piston diameter (MD 5131) is greater than zero and greater than rod diameter (MD 5132 or MD 5133).
3
Save and restart
Save the corrected values, reset the alarm, and restart the system.

DIY Feasiblehigh confidence

Call a technician if:

·If the alarm persists after correcting machine data
·If access to MD parameters is restricted or unclear

Prevention

Double-check machine data values during setup
Use documentation for valid parameter ranges

Common Mistakes

Entering zero or negative values for diameters
Confusing piston and rod diameter fields
