Abstract
A motor controller for use in a motor system includes a mode select circuit, a fault detection circuit, a protection logic circuit, and a motor control circuit. The mode select circuit sets the motor controller in one of an internal protection mode and an external protection mode. The fault detection circuit detects whether the motor system is operating in a normal operation state or a fault state. If the motor system is operating in the fault state, the protection logic circuit outputs a protection signal in the internal protection mode, and keeps the protection signal inactive while activating an external diagnostic signal in the external protection mode. The motor control circuit controls a motor of the motor system in response to a speed control signal when the protection signal is inactive, and in response to the protection signal when the protection signal is active.
