Let’s take a look at a practical tuning exercise and take a closer look at the real effect of the various gains. Digital servo drive and motor with encoder feedback will be used to illustrate the effects of the various gains, as well as to provide some practical guidelines. One of the best ways … [Read more...]
Case Study: High precision XY gantry with self-correcting XY orthogonality system
Primatics was contracted to design and build a 5-axis, high precision sorter system. Two of the axes were to be in a gantry form of a 500 mm travel Y, Y’ with a 1300 mm travel X cross axis supported by the Y carriages. The X carriage was to carry a 50 mm travel Z axis which in turn would carry the … [Read more...]
Understanding How Feedback Encoder Devices Operate
Feedback is used in closed loop systems in applications across all markets to control speed and/or position, and it has an important role in keeping equipment operating smoothly and accurately. This guide provides an overview on open and closed loop systems, hall sensors, and also covers encoder … [Read more...]
Incremental Encoder Signals
Incremental encoders are used on motors and equipment as feedback devices to determine position and direction of machinery. Motor controllers can also use position information from the encoder to commutate the motor and calculate velocity for speed control. The incremental encoder is a critical … [Read more...]
Reimagining Reflective Encoders
Traditionally, reflective encoders have been considered a lower end option used when cost was more important than options. Whether needing high CPR, an index channel or compact sizes, it's time to reevaluate reflective technology. New encoders are still economical but now offer improved performance … [Read more...]
