Abstract: The invention relates to drive controlled by a sequence of pulses and which in place of a stepper motor with its associated circuit makes use of a continuous displacement motor, such as a DC motor, which may be directly connected with a process computer. The motor is coupled with an incrementally operating displacement sensor which for each displacement increment to be caused by a control pulse, generates precisely one sensed pulse. The sensed pulses and the control pulses are fed to an up-down counter via an electronic separating filter. The output signal of the counter and that of a periodically upwardly counting ancilllary counter is used for addressing a ROM whose output bit pattern controls the power switching stages of the DC motor or other continuous drive.
