Heidenhain

Heidenhain is a leading German manufacturer of precision measurement systems, rotary encoders, linear scales and CNC control systems for high-precision machine tool engineering. With a catalog of 1,089 products, Heidenhain delivers the most accurate position measurement systems in the world for CNC machining centers, coordinate metrology, semiconductor manufacturing and advanced measurement technology.

Heidenhain rotary encoders are the most widely used products in CNC machining machines worldwide. The ERN series (incremental) and ECN/RON series (absolute) rotary encoders are used for shaft rotation feedback in servo motors and drive motors in CNC machines, robots and automation systems. Resolutions up to more than 33 million steps per revolution and accuracies better than ±5 arcseconds are standard in the high-precision product line. Interface options include 1 Vpp sinusoidal, EnDat 2.2 serial, DRIVE-CLiQ and BiSS-C.

Heidenhain linear encoders and length measurement systems measure the linear position of axis slides, tables and carriages in CNC machines with sub-micrometer accuracy. The LC 115/195 series linear encoders provide absolute measurement with resolutions to 1 nm and are housed in sealed enclosures protecting the scale from coolant splashes, chips and dust. Glass scales, steel scales and special integrated scales are available for various machine configurations.

Heidenhain CNC controls, including the TNC 640, TNC 7 and iTNC 530, are leading open CNC systems for milling and machining centers. They support simultaneous 5-axis machining, HSC (high-speed cutting), contour operations and advanced milling functions via an intuitive conversational programming interface or DIN/ISO-compatible NC coding. Heidenhain position displays (ND series) visualize position feedback from single or multiple measurement axes for manually operated machines.

At Verkopershulp.nl you will find the complete Heidenhain range including rotary encoders, linear encoders, connection cables, plug adapters and spare parts. Our technical experts help you select the correct encoder for your machine axis and the compatible connection interface.

History

Heidenhain was founded in 1889 by Wilhelm Heidenhain as a manufacturer of mechanical engraving and photoengraving systems in Traunreut, Germany. In the 1950s, the company specialized in the production of photoelectric measurement scales for metrology applications. Heidenhain was a pioneer in applying optical diffraction gratings for high-resolution position measurement, a technology that still forms the basis of the precision encoders today. In the 1970s, Heidenhain expanded into CNC control systems and digital display technology. Today Heidenhain has more than 3,200 employees and supplies the most accurate encoders and measurement systems in the world to more than seventy countries.

Frequently Asked Questions

What is the difference between an incremental and absolute Heidenhain encoder? ▾
An incremental Heidenhain encoder (e.g. ERN series) generates a continuous series of pulses on rotation but does not know its absolute position at startup. After power loss, homing (return to reference position) is required. An absolute encoder (e.g. ECN/EQN/ROC) knows its absolute position immediately after power-up via a unique binary code per angular position, making homing unnecessary.
Which Heidenhain encoder interface is compatible with my servo drive? ▾
Heidenhain encoders are available with various interfaces: 1 Vpp sinusoidal (for Heidenhain interpolation electronics), EnDat 2.2 serial (high-speed serial for direct CNC use), DRIVE-CLiQ (for Siemens Sinamics drives) and TTL/HTL rectangular (for simple applications). Consult the specifications of your servo drive for the required interface.
What accuracy do Heidenhain linear encoders offer? ▾
Heidenhain linear encoders of the high-precision LC series offer position accuracies of ±0.1 µm to ±5 µm over the full measurement length. Glass scales achieve the highest accuracy; steel scales are more robust for longer measurement lengths up to 3000 mm. The resolution of modern linear encoders goes to 1 nm when using Heidenhain EXE interpolation electronics.
Are Heidenhain encoders available for use with Siemens DRIVE-CLiQ? ▾
Yes, Heidenhain supplies special absolute encoders (ECN 1123/EQN 1135) with DRIVE-CLiQ interface directly compatible with Siemens Sinamics S120 and S210 servo drives. DRIVE-CLiQ provides automatic encoder recognition, digital diagnostics and fast communication without a separate encoder interface card in the drive.
How do I replace a Heidenhain encoder on a CNC machine? ▾
To replace a Heidenhain encoder, note the type ID (on the sensor label or connection cable piece) and the interface version (EnDat 2.1 vs 2.2). Ensure the new encoder has identical specifications for shaft coupling, bore, flange version and electrical interface. After installation, re-parameterization of the CNC machine control (encoder parameters and axis calibration) is required.
Does Verkopershulp.nl supply spare parts for Heidenhain measurement systems? ▾
Yes, Verkopershulp.nl supplies an extensive range of Heidenhain products including rotary encoders, connection cables, plug adapters, scanning probes for the EXE series and mounting materials. For damaged or obsolete encoders, we can advise on the correct replacement or technically equivalent alternatives.
Does Verkopershulp.nl offer technical support for Heidenhain encoder installation? ▾
Yes, Verkopershulp.nl has technical specialists who help you select the correct Heidenhain encoder for your CNC machine, servo drive or measurement system. We advise on encoder type, interface selection, connection method and mounting requirements.
