ABSTRACT:
A motor drive having a sensing input for sensing fault conditions and a speed control input for receiving a speed control signal. The variable speed motor drive is suitable for being powered by a power supply coupled to a supply input and controls motor speed in a variable speed motor based on the speed control signal such that the motor speed corresponds to the level of the speed control signal. The disclosed motor drive includes a power interrupter, coupled between the supply input and the variable speed motor, for controllably interrupting power to the motor as well a a drive controller coupled to the motor drive for monitoring the sensing input and causing the power interrupter to interrupt power when a fault condition occurs. The drive also provides that speed control signal to the speed control input at a level which stops the motor when a fault condition occurs.
