What it represents
A rotary-motion qualifier identifies movement or torque in one direction of rotation. A rotary indication records the direction assigned to a mechanical movement. Its viewpoint matters when the mechanism and its control circuit are shown in separate drawings.
Use a stated viewing reference where rotation direction is significant. The arrow does not substitute for actual machine terminals, wiring or a phase-sequence specification.
How to read it
- Relate the direction to the described mechanism and viewing convention.
- An arrow direction is not a complete motor phase-sequence or rotation instruction.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Relate the direction to the described mechanism and viewing convention.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
An arrow direction is not a complete motor phase-sequence or rotation instruction.
