Drive: Motor overspeed

What does F07901 mean?

The motor's actual speed has exceeded its configured maximum permissible limit, either in the positive or negative direction. This indicates a potential loss of speed control, incorrect parameterization, or an external force driving the motor. Exceeding the motor's rated speed can lead to mechanical failure, rotor damage, or safety hazards.

   Increase the hysteresis for the overspeed signal (p2162) if nuisance tripping occurs, ensuring it doesn't compromise safety.
