Siemens Drive Fault Code 7902 ((free)) Jun 2026

In the drive parameters (using STARTER or Startdrive):

The Siemens drive fault code (often displayed as F07902 ) indicates a "Motor Stalled" condition . This occurs when the drive detects that the actual motor speed has deviated from the set speed for longer than a specified delay time. Core Causes siemens drive fault code 7902

However, a critical nuance often missed: In some Siemens drive firmware versions, can also indicate a wire break or short circuit in the temperature sensor feedback circuit , rather than actual overheating. This dual nature makes it a tricky fault to diagnose without systematic testing. In the drive parameters (using STARTER or Startdrive):

The motor is struggling to turn the mechanical load. This dual nature makes it a tricky fault

Tell me the exact Siemens drive model (e.g., SINAMICS G120 CU240E-2 ) and whether you have an encoder or are running in V/f or vector control.

Increase p1610 (static torque setpoint) if stalling happens at low speeds.
