Absolute Length Gauges for Shop-Floor Metrology
The conditions surrounding production environment metrology place special demands on position measuring systems used for workpiece inspection in shop-floor metrology. The very principle of inductive systems involves disadvantages such as temperature sensitivity or nonlinear behavior. A length gauge recently developed by HEIDENHAIN in Traunreut, Germany, now combines the benefits of incremental optical devices and absolute [...]
Rotary Encoders for Highly Dynamic Servo Drives
Controlled servo drives are used in many areas of automation technology, robotics and handling systems as well as in the drive technology of production machines and machine tools. The requirements regarding dynamics, speed stability and rigidity necessitate ever increasing gain factors in the control loops. The position encoders used are an important factor in the [...]
Rotary Encoder Selection :: Consider accuracy, position or velocity control, speed stability, power loss, and ban width, other attributes when selecting a rotary encoder or encoder technology.
Controlled servo drives are used in many areas of automation technology, converting, printing, handling, and robotics including production machines and machine tools. The selection of a rotary encoder or encoder technology for use within the system depends on the accuracy requirements of the application, whether it is position and/or velocity control.
