Re-run the motor identification at standstill ( p1900 = 2 ) to ensure the drive has accurate data from the motor's nameplate (p304–p311).
He checked the DC link voltage. The capacitors in the line module were humming, charged and ready. But the second motor siemens drive fault code 7902
To avoid recurring F07902 disruptions, implement these long-term maintenance strategies: Re-run the motor identification at standstill ( p1900
Run the motor identification routine (p1900 or p1910) to allow the drive to measure the motor resistance and inductance. Step 3: Adjust Acceleration and Torque Limits siemens drive fault code 7902
