F07925

Drive: Torque/speed out of tolerance

Siemens · DCM

What does F07925 mean?

This fault indicates a deviation between expected and actual motor performance. If p2193=1, the torque deviates from the defined torque/speed envelope characteristic. If p2193=2, the speed signal from an external encoder (p3230) deviates from the internal speed (r2169). This suggests a mechanical issue, an incorrect encoder setup, or improper drive parameterization.

Complete Troubleshooting Guide

  1. 1

    Check the mechanical connection between the motor and the load for any signs of slippage, breakage, or misalignment.

  2. 2

    Verify the functionality and accuracy of the external encoder (if p2193=2 is active) and its connection to the drive.

  3. 3

    Adapt the drive's parameterization, especially load monitoring and speed/torque limits, to correspond with the actual load characteristics.

  4. 4

    Ensure that the torque/speed envelope characteristic is correctly defined for the application.
