Patent ID: 8279565

Claim:
A method of operating an overcurrent protection control system, comprising; monitoring an operational state of a motor; defining a first threshold current value of the control system corresponding to a first operational state of the motor; defining a second threshold current value of the control system corresponding to a second operational state of the motor; sensing an amount of current being supplied from a power source to the motor; dynamically setting an operational threshold current value depending on the monitored operational state of the motor, wherein the dynamically set operational threshold current value is set at the first threshold current value if the motor is determined to be operating in the first operational state, and wherein the dynamically set operational threshold current value is set at the second threshold current value if the motor is determined to be operating in the second operating state; comparing the sensed current amount and the dynamically set operational threshold current value; and electrically isolating the power source from the motor if the sensed current amount exceeds the dynamically set operational threshold current value.
