: Incorrect motor phase lead connections or disconnected motor cables.
: Marcus checked the motor cables. A loose connection or a swapped phase (U and W cables) is a classic culprit that sends the drive into a tizzy. The Parameter Trap : Leo pulled up the drive parameters on the BOP-2 operator panel . "The threshold is set tight," he noted. The Resolution "Look at the delay," Marcus pointed to siemens drive fault code 7902
, this fault is frequently tied to asynchronous motors that haven't undergone proper static optimization. You can view the specific fault history and timestamps using the Siemens STARTER software TIA Portal specific parameter numbers for a particular Siemens drive series, like the : Incorrect motor phase lead connections or disconnected
Increase the acceleration time to give the motor more time to reach speed without hitting the stall threshold. If you are using a SINAMICS G120XA The Parameter Trap : Leo pulled up the
The load is too heavy for the motor to start or maintain rotation, causing it to stall. Incorrect Motor Data:
