Faulty speed feedback from an encoder or incorrectly connected motor cables (e.g., swapping U and W phases) can cause the drive to "think" the motor is stalling. Brake Malfunction:
"It’s not the PLC," Elias murmured, scrolling through the parameters. "The PLC is talking to the drive just fine. The Profibus light is green. This fault... it means this drive isn't hearing its partner." siemens drive fault code 7902
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 Faulty speed feedback from an encoder or incorrectly
