The wiring of multiple bit parallel encoders for a multi-axis application is very time consuming. The synchronous-serial-interface is an alternative interface option for such applications. How it works: The position value is transmitted synchronously to a clock signal sent from the control system...

...the electronic signals are amplified and converted, they are then available for the evaluation of the position. In some applications the encoder shaft makes one revolution for one complete cycle of machine operation (angular rotation of a crankshaft in a punch press or rotary indexing table). Absolute...

Rotary and linear encoders are standard equipment in today's automated motion systems. Both types, generally, are optically based, relying on light passing through or reflecting off a scale and then interpreted by optoelectronics. For rotary sensing, this works well, but the same cannot be said...

...for automotive ABS applications, eliminates the need for an extra gear-tooth sensor or rotary-pulse generator. Simple bolt-on installation requires no extra brackets or couplings, and the air gap reportedly can't go out of adjustment. The sensors are built on Fafnir Survivor PT bearing platforms, which...

...use of a metal-tape linear encoder system, a rotary absolute encoder, or laser reflectometer. A relatively new technique is designed to overcome many of the drawbacks these methods entail. It employs a linear profile that is somewhat analogous to the stainless-steel tape used by some linear encoders...

An encoder is an electro-mechanical transducer that converts mechanical rotary motion into digital. signals for the control of machinery. The encoder produces a square wave signal as the shaft rotates. Speed, position, servo feedback, etc., can be determined through proper processing of this signal...

...application, notes Keller. For simple tasks, indirect systems such as rotary encoders on motors calculate positioning data with sufficient accuracy. Although this method offers clear advantages in velocity-control loops, mechanical errors affect results. Consequently, positioning accuracy is only around 0.1...
