A method of motor enablement is described in which a capacitor is charged or discharged depending on whether or not the current flowing through an inverter driving the motor is above a reference current. When the motor is in an enabled state, the motor is disabled if the voltage across the capacitor rises above a first (upper) voltage threshold. Similarly, when the motor is in a disabled state, the motor is enabled if the voltage across the capacitor falls below a second (lower) voltage threshold. |
