The proposed programmed control device for a stepping motor contains a setting unit, a pulse distributor, a multichannel amplifier, a controlled threshold element, AND logic elements, OR logic elements, a fault detector, and additionally, a microprocessor test unit. The output of the setting unit is connected to the input of the pulse distributor. The output of the pulse distributor is connected to the input of the amplifier. The inputs of the test unit are connected to the terminals of the windings of the stepping motor and the output of the fault detector, and the output is connected to the input of the setting unit.
