Limited two-way rotary-motion qualifier

What it represents

This qualifier identifies rotary movement in both directions over a limited travel. A mechanism can move clockwise and counterclockwise between defined positions without rotating indefinitely. This distinction is useful for actuators and position-changing mechanisms.

State the end positions or stops in the mechanism documentation. The qualifier itself supplies neither angular travel nor the electrical control sequence.

How to read it

• Record the mechanism's defined end positions separately.
• A limited-travel qualifier gives no numerical angular range.

Information to show or reference

• Identify the associated device, circuit or diagram boundary.
• Record the mechanism's defined end positions separately.
• Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
