Unlike fault 7900 (Motor Blocked), which usually occurs at very low speeds, typically triggers when the motor enters a current limit above a specific speed threshold. The drive monitors the deviation between the speed setpoint and the actual speed feedback (or estimated speed in encoderless mode). Primary Causes & Parameters
