This representation identifies a permanent-magnet stepping-motor function.

## What it represents

This representation identifies a permanent-magnet stepping-motor function.
Cross-reference the phase/drive connections and the specified step-control interface.
A stepping motor requires a drive sequence rather than an ordinary continuously applied DC supply assumption.

## How to read it

- Cross-reference the phase/drive connections and the specified step-control interface.
- A stepping motor requires a drive sequence rather than an ordinary continuously applied DC supply assumption.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Cross-reference the phase/drive connections and the specified step-control interface.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

A stepping motor requires a drive sequence rather than an ordinary continuously applied DC supply assumption.
