Abstract
An accommodation circuit for converting the energization pattern provided to a step motor by a logic sequencer is disclosed herein. The circuit provides a series of override signals in response to the clock controlling the logic sequencer. The override signals are combined with the energization signals provided by the logic sequencer to convert the energization pattern to a predetermined alternate pattern.
Claims16
An accommodation circuit for use in conjunction with a step motor of the type controlled by a clock, a logic sequencer and a series of power drivers, said logic sequencer providing a series of energization signals, defining an energization pattern, to said power drivers in response to said clock, comprising, in combination:
- conversion means, responsive to said clock, for providing a series of override signals to said power drivers for combination with said energization signals to convert said energization pattern to a predetermined alternate pattern;
- initialization means for initializing said conversion means;
- and
- sequence-matching means for sequentially matching said conversion means to said logic sequencer whereby said override signals are properly coordinated with respect to said energization signals.
