Compatibility

• HEIDENHAIN Linear Enclosures & Scales: LF, LS, and LB series incremental/absolute encoders.
• HEIDENHAIN Angle & Rotary Enducers: ROD, RON, and RCN series.
• Length Gauges: HEIDENHAIN Metrology length gauges utilizing App 11 µ App or 1 Vpp outputs.
• Sensors: ±10V industrial standard temperature sensors for thermal expansion correction.

Applications

• High-precision dimensional inspection and quality control laboratories.
• Manual and automated coordinate measuring machines (CMMs).
• Specialized tooling, alignment jigs, and optical test benches.
• Multi-axis positioning tasks requiring strict tolerance sorting and sorting routines.

Guide for Maximum Efficiency

• Datum Management: Leverage the dual datum memory banks to quickly toggle between reference frames during complex multi-step inspection routines without resetting your baseline.
• Error Monitoring Configuration: Keep the error monitor parameter set to FRQ.+CONTAMINATION. This catches optical signal degradation early before dirty scales result in out-of-tolerance batch processing.
• Firmware Diagnostics: Use the built-in diagnostic screen via the setup menu to routinely check individual signal amplitudes to ensure your optical scale optics remain clean and optimal.

Frequently Asked Questions

What encoder signal types are natively supported by the HEIDENHAIN ND 287 (ID 636-287-01)?

The base unit supports 11 µApp or 1 Vpp, and EnDat 2.1/2.2 absolute/incremental encoder signals through its modular interface configuration. Additional inputs can be integrated via secondary plug-in expansion modules.

Can this digital readout handle temperature compensation?

Yes. By installing an optional analog module, you can connect a ±10V temperature sensor. The ND 287 will process the thermal input and dynamically execute linear expansion corrections based on user-defined coefficients.

How do I clear an error code or contamination warning on the screen?

If an error condition such as contamination or frequency overflow occurs, press the C key on the front keypad to acknowledge and clear the warning message once the underlying issue is resolved.

Is data transfer possible to external computers?

Yes, the unit features standard RS-232-C/V.24 and USB Type B data interfaces, allowing users to export live data streams, measurement logs, and parameter configurations directly to data acquisition hardware or PCs.
