The Siemens drive fault code indicates a "Motor Stalled" condition. This occurs when the drive detects that the motor speed is significantly below the expected setpoint while it is delivering maximum torque or current. Deep Technical Insight: Why it Occurs
: Rerun the motor data identification at standstill by setting siemens drive fault code 7902
They moved to the lower section of the cabinet. The lights on the second motor module were dark. Completely dark. F07902 The Siemens drive fault code indicates a
G120XA solution to warning F7902 motor out of step - Siemens The lights on the second motor module were dark
: Redo the motor data identification (p1900=2) and static optimization.
In Siemens SINAMICS drives (like the G120 or S120), indicates a Motor Stalled condition . This happens when the drive detects that the motor has stopped rotating for longer than the set delay time, even though the drive is trying to run it.
