| Cause | Description | |-------|-------------| | | Open circuit in U, V, or W phase cable | | Motor winding failure | Open or severely imbalanced motor winding | | Contactor/MCCB issue | Output contactor opened or faulty | | Phase loss due to loose terminal | Loose connection at drive output or motor terminals | | Current sensor failure | Rare, but possible internal drive hardware issue |
A very specific question!
Reconsider the operating conditions or increase the motor/drive capacity. Hardware Failure: In rare cases, internal failure of the itself can cause this error. yaskawa error code a910
) may be set too low or is unsuitable for the current operating conditions. Hardware Failure: In rare cases, a failure within the unit itself can trigger false warnings. Recommended Solutions Check Mechanicals: | Cause | Description | |-------|-------------| | |
Check Pn52B (Overload Warning Level). If the application naturally runs high, this may need to be increased slightly. ) may be set too low or is
This code signals that the motor is operating at a load or torque level that exceeds its continuous rating for a significant period. If ignored, the drive will eventually trip to protect the hardware. Yaskawa America Primary Causes and Solutions Mechanical Overload:
Unlike a "Fault" (which immediately stops the motor), a "Warning" allows the motor to continue running while notifying the operator of an impending issue. Primary Causes
