What does 59 mean?

The output current has exceeded the value set in parameter 4-18 (Current Limit). This indicates that the motor is drawing more current than configured, possibly due to overload, incorrect motor data, or an inappropriately set current limit. Persistent current limiting can restrict motor performance and lead to unexpected shutdowns.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Check the application for excessive mechanical load, binding, or other factors causing high current draw from the motor.
