Abstract: An electronically commutated motor driving module for driving a motor includes a voltage detector, an electronically commutated motor driver, a current detector, a voltage converter, and a controller. The voltage detector detects supply voltage to generate a voltage detection signal. The electronically commutated motor driver is supplied by the supply voltage to generate, according to an electronically commutated signal, an operating current for driving the motor. The current detector detects the operating current to generate a current detection signal. The voltage converter converts the supply voltage into an internal voltage. The controller is supplied by the internal voltage and generates the electronically commutated signal according to a plurality of control parameters. When the controller determines that a specific event has happened according to the control parameters, the controller stops generating the electronically commutated signal and then stores the control parameters.
