Description:

Abstract:

An apparatus is disclosed for monitoring the motion of a stepping motor in response to input drive pulses from a control circuit. A velocity transducer is coupled to the stepping motor and produces a velocity and feedback signal. A logic circuit is responsive to the input drive pulses and the velocity feedback signal and produces an error signal in response to the stepping motor failing to respond to the input pulses.
