Description

The ELM310 is an interface circuit for use between high speed logic outputs and four phase stepper motor driver circuits. By suitably debouncing mechanical switches, the circuit could also be used for manually controlling stepper motors as well.

This circuit ELM310 supports two popular modes of operation, and can be switched between the two 'on the fly'.

The full-step, or single phase wave mode, as it is sometimes called, is entered into at powerup. This mode provides sequential single phase output signals for driving a variety of circuits with only one output active at any one time.

The other mode that the ELM310 supports is the half-step. In this case, there are eight distinct output patterns as opposed to the four for the full-step mode. For each step, the pattern alternates between a single winding being energized, and two adjacent windings, providing eight steps in total.
