When it comes to accurate measurements, precision has a massive role to play. Well, one of the most effective devices to offer you precision motion control is the rotary absolute encoder. With resolutions that go up to 25-bit, absolute encoders offer incredibly accurate angular measurements. And that’s the degree of precision, automation, robotics, and semiconductor manufacturing industries need.
What makes these devices indispensable for many industrial applications is they ensure every movement is predictable and precise.
Why Precision Motion Control Matters?
Better Quality Control: When you get precise movements, every operation is done the same way every time. That’s vital for quality control.
Reduced Rework: Accurate motion control results in lower rework, saving resources and time.
Increased Output: repeated precise and automated operations increase system efficiency resulting in higher output.
Greater Safety: Precise motion control helps prevent accidents by ensuring that movements are within safe parameters and predictable.
How do Absolute Encoders Provide Precision Motion Control?
Motion control systems call for a high level of precision, and that’s where rotary absolute encoders step in as the way to go. Here’s how absolute encoders - delivering precision motion control - support higher efficiency, cost-effectiveness, and safety:
1. Accurate Position Feedback
With absolute encoders, you get accurate and real-time position feedback - a must-have for robotic arms and automated systems. With this position feedback, the system makes precise adjustments on the fly. This further ensures that the system achieves the desired movement with minimal error. The AV6A or AV6M Avtron Encoder model is a perfect fit for use in robotic arms, with its robust construction and high precision capability. And if heavier duty is required due to extended shaft loads or vibration, the AV30 or HS40 can provide the dependable accuracy even in the toughest applications.
2. Holding Position Even After Power Loss
What’s best about absolute encoders? They can remember their position even after power cuts. This is what’s needed in cases where the system needs to restart exactly from the same position where it left off before the power cut. No recalibrating, no resetting, and no waste of time.
3. Improving Closed-Loop Control Systems
In closed-loop control systems, the encoder continues to provide position feedback so that the system can adjust the movements of the motor in real-time. This continuous feedback loop is what’s needed to maintain high precision in applications like robotics, cranes, and industrial automation.
4. Helping in Multi-Axis Control
In complex systems, like in 5-axis CNC machines or advanced robotics, you need to control multiple axes simultaneously. Here, absolute encoders deliver position information for each axis. The result? All the axes work together smoothly, attaining the required motion with high accuracy. The Avtron Encoder model that’s fit for use in 5-axis CNC machines and advanced robotics is AV6A or AV6M.
5. Enhancing Repeatability
Repeatability is crucial in manufacturing - the same thing needs to be done the same way, every single time. Rotary absolute encoders help achieve this much-needed repeatability by delivering consistent position information, ensuring every cycle of a robot or machine is identical to the last one.
6. Supporting Complex Movements
Robotic applications often involve multi-dimensional, complex movements. Here, rotary absolute encoders offer the much-needed precision motion control to enable robotics to do intricate jobs with accuracy.
What are the Applications of Absolute Encoders?
Wherever accurate positioning matters, absolute encoders find use. Here are some applications of these devices:
Elevators and Lifts
With these encoders, you get smooth acceleration and deceleration in vertical transport systems. They monitor shaft position and motor speed, preventing jerky movements and enabling consistent, safe passenger experiences. To get superior results, we would suggest you to use our AV6A or AV6M Avtron Encoder model in elevators or lifts.
Steel Plants
Heavy duty absolute encoders are a must in cold & hot mill steel plants, specifically in complex applications such as loopers, where they must provide accurate positioning information for the looper’s angle while being subject to high temperature fluctuations and vibration. This ensures precise control over the tension of the metal strip and prevents damage. Some heavy duty Avtron Encoder models that perform incredibly under the harsh environment of steel plants are AV30 and HS40.
Cranes
When you use these encoders in cranes, they give precise, continuous position feedback of the position of the crane at all time during standstill or while transitioning from point A to point B. This ensures safety and accuracy by holding position info even after power outage. Once again, our AV30 and HS40 Avtron Encoder models deliver excellent results when used in cranes.
Mounting a Rotary Absolute Encoder
Rotary absolute encoders are typically mounted on the rear end of a rotating shaft, commonly found in electric motors. However, to enhance reliability, some original equipment manufacturers (OEMs) and industrial integrators install rotary absolute encoders on pillow blocks or rotating rolls. This approach helps improve the accuracy of positional data, which can otherwise be compromised by misalignments, slippage, or other mechanical disturbances.
