MRP 8000 angle encoder module: unfazed by off-axis tilting loads
The MRP 8000 angle encoder modules are shipped to the machine manufacturers as complete assemblies with specified characteristics. They combine high-resolution measuring technology with a highly stable bearing. HEIDENHAIN has already completed the necessary assembly and adjustments of all individual components.
Particular advantages of this highly integrated system solution:
- Replaces the customer's bearing
- Unfazed by off-axis tilting loads
- All critical mounting processes eliminated
Angle encoder modules from HEIDENHAIN make the setup of high-precision rotary axes much easier, particularly for manufacturers of measuring machines, laser trackers, wafer handling robots, electrical discharge machines, and machines for micro-precision manufacturing.
The angle encoder modules are characterized by:
- High measuring and bearing accuracy
- Very high resolution
- Very high repeatability
- Low starting torque
- Constant movements
GAGE-CHEK 2000 evaluation unit: the compact all-in-one device for reliable 1-D measured-value acquisition
HEIDENHAIN presents the new GAGE-CHEK 2000 evaluation unit for reliable measured-value acquisition in a production environment. The sturdy all-in-one device is highly well suited for positioning tasks on measuring devices and positioning equipment, and for measuring-machine retrofits. The GAGE-CHEK 2000 supports the user with intuitive operation over the touchscreen and the context-sensitive display of functions and features.
ERP 1000 modular angle encoder: versatile, accurate, and sturdy
When the new modular angle encoders of the ERP 1000 series were developed, HEIDENHAIN placed the main emphasis on the following three characteristics:
- Flexible integration in the customer's overall system
- Accuracy of the measured values
- Stability of the measured-value acquisition
These goals were achieved through a combination of the modular design and the first use of the HEIDENHAIN signal-processing ASIC HSP 1.0 in an angle encoder.
Wide variety of variants: circular scales are available as full circles and as segments with various diameters
Easy mounting: non-paired system with generous mounting tolerances and automated signal adjustment
Simple electrical connection: Wide selection of cable and connector versions
Accuracy grades as fine as ±0.9 angular seconds
Interpolation error down to ±0.02 angular seconds
Position noise RMS down 0.002 angular seconds
Consistently high quality of the scanning signals over the entire lifetime
Signal stabilization without amplification of the noise component
Consequently, the ERP 1000 modular angle encoders are particularly well suited to applications demanding exceptionally constant speed control or high position stability at standstill.
HEIDENHAIN signal-processing ASIC HSP 1.0: for permanently stable measured values
Some of the special characteristics of the ERP 1000 modular angle encoders or of the LIC, LIDA, and LIF series of exposed linear encoders, as well as the LIP 6000, are the result of the new HEIDENHAIN signal-processing ASIC HSP 1.0. It ensures a consistently high quality of the scanning signals over the entire lifetime of the encoders. It does this by continuously monitoring the scanning signal.
If the signal amplitude decreases, the HSP 1.0 readjusts it by increasing the LED current. The ensuing increase in the LED light intensity hardly affects the noise level in the scanning signals at all, even when there is a high degree of signal stabilization—quite contrary to systems in which the gain is made in the signal path. At the same time, the HSP 1.0 also ensures that the signal retains its original, ideal form, even if there is contamination.
Positioning and drive technology from ETEL: highly accurate or with high torque
With its linear and torque motors as well as the AccurET controller, ETEL is presenting high-accuracy direct drives for motions in the nanometer range and also high-torque systems for industrial applications.
Particular strengths of the drives and motion control systems from ETEL are:
- Zero-cogging design
- Optimum speed stability
- Very high control-loop performance
