Your application; our expertise in encoder technology

In addition to accuracy and reliability, the mechanical and electronic connectivity of encoders is a key selection criterion to the manufacturers of machines and equipment used across all industries. That’s why HEIDENHAIN offers encoders featuring both a wide variety of interfaces and identical mounting dimensions, thus enabling a standardized design that is independent of the subsequent electronics used.

Linear and angle encoders, as well as rotary encoders, are available with the serial interfaces of all common controls, including HEIDENHAIN, Siemens, Bosch, Fanuc, Panasonic, Mitsubishi, Yaskawa, and many more.

Secondary encoders: significantly greater accuracy for robots

A seventy- to eighty-percent increase in the absolute position accuracy at the tool center point enables industrial robots to perform more demanding tasks in assembly technology and in the machining of large workpieces. Improvements of this magnitude can be achieved through the use of secondary encoders that are added to the primary motor feedback system. Secondary encoders ascertain the actual position of each robot joint, taking into account the zero position error and reverse play, as well as the backlash that arises during machining.

A typical solution for high-accuracy robots consists of a HEIDENHAIN inductive rotary encoder from the EBI 1100 or EQI 1100 series for the purpose of motor feedback, and a WMKA/WMRA angle encoder from AMO serving as the secondary encoder.

The formula for success at machine tool accuracy

At the SPS, HEIDENHAIN presents rotary encoders, angle and linear encoders for the highly dynamic motion control of machine tools and at the same time for highly accurate position measurement. They are also very impressive with regard to high mechanical and process reliability.

Simple and uniform operating data diagnostics – with Connected Machining

At HEIDENHAIN, the user at the control is the center of digital order management of his milling or turning machine. The options, software and hardware solutions from Connected Machining in the HEIDENHAIN control provide him with convenient access to all necessary information in the company network. At the same time, the user can return data from production to the process chain, so that all parties involved can always work with real data from production. At the SPS IPC Drives, HEIDENHAIN focuses primarily on the aspects of uniformly digital operating data diagnostics. A demo application on a TNC 640 control shows impressively how easy it is with Connected Machining to receive and edit job and production data directly at the control.

System monitoring benefits from interface diversity

One key advantage of serial interfaces is their diagnostic functionality. This capability supports the analysis of complex machines, thus providing an important contribution to Industry 4.0 technology, and is available with other interfaces in addition to EnDat. With the idea of valuation numbers that describe the basic properties of an encoder, HEIDENHAIN has significantly simplified diagnostics. In addition, HEIDENHAIN is the only encoder manufacturer to offer a diagnostic tool for all encoders with absolute or incremental interfaces: the PWM 21 adjusting and testing device and ATS software. This enables users to check the condition of the encoders both during machine operation (online diagnostics) and during assembly or repair (offline diagnostics).

Inductive rotary encoders for highly dynamic drives

High control quality and system accuracy as well as very high tolerance, especially against vibrations and electromagnetic influences—these are the strengths of the ECI/EQI 1100 and ECI/EQI 1300 inductive rotary encoders without bearings. This makes them ideal for position feedback for highly dynamic applications.

All variants support safety integrity level SIL 2, category 3 PL d. Additional measures in the control can enable attainment of even SIL 3, category 4 PL e. And they offer a mechanical fault exclusion against loosening of the shaft or stator connection.
