Image Processing: Color Extraction
This white paper introduces the idea of image processing from the basics. The topic covered in this document is color extraction, which reduces the amount of data that must be processed. To achieve both high performance and speed, it is important to select the right method of extracting color information for the specific target.
Feedback Sensors Keep Servo Motors on Target
Author: Gene Matthews, product manager for Kollmorgen
Fundamentally a servo system can perform no more accurately than the accuracy of the feedback device controlling it. In addition, errors in speed or position can be introduced into the system by the less than perfect mechanisms that transfer the motor power to the load. Environmental factors like electrical noise or temperature may also introduce positioning errors. Sometimes the errors are acceptable. More frequently, however, they are not. After all, servo motors can be expensive, and the expectation is that they will be the most reliable and accurate of all positioning devices.
When it comes to high-performance servo applications, feedback devices fall into several different categories. In this white paper, learn how each offers unique advantages and disadvantages, both electrical and mechanical, which make one better suited for a particular application than another.
Capturing and Simulating Rotational and Jitter Angle-Based Measurements
Author: CAS Dataloggers
Capturing and simulating the high-speed rotations involved in automated machines and test rigs often plays a major role in industrial applications. Common requirements are accurate speed measurement over a large range of operation, detection of speed changes, capturing jitter, jitter simulation and angle-based data acquisition. In this white paper, application specialists present some practical approaches to accomplishing these tasks.
How to Select the Right Positioning Sensor Solution
To accommodate today's rigorous performance and reliability demands, manufacturers need to implement positioning sensor solutions that can provide continuous operation and the highest level of accuracy. Sensors using a unique RLC operating principle are designed for accuracy, flexibility and durability to accommodate the widest range of applications and complement production efficiency goals.
This white paper will serve as a valuable industry guide in selecting the ideal positioning sensor by defining how sensors utilizing the RLC operating principle work, describing the benefits RLC sensors deliver, and providing a comparison of similar sensing technologies.
- iPOS3604 VX intelligent drives, and provides connectors (motor, encoder feedback and I/O signal) for each drive through a CANbus link.
- M12 connectors provides EtherNet/IP and Modbus TCP access to IO-Link sensor process, event and service data with Class 1 (implicit) and Class 3 (explicit) interfaces.
- RS-232 link offers access to all drives, for setup and testing, using a standard PC. It works with dc brushed, (rotary or linear) brushless, or step motors (4x144 W, 4x36 V).
- LVDTs have a spring-loaded shaft running in a precision sleeve bearing and connected to the core of an LVDT. Measurement repeatability is 0.6 µm or better.
