HEIDENHAIN ACANTO
Comprehensive diagnostics functionality thanks to EnDat 2.2 interface

Industry 4.0, among other factors, concerns gaining more information about the quality of each individual machining step and each quality inspection step. HEIDENHAIN ACANTO length gauges provide realistically analyzable information about the measurements. This is made possible with the bidirectional EnDat 2.2 interface. In addition to providing the position value, the interface also provides further information about the length gauge: 

  • Valuation numbers supply data about the momentary status of the encoder. These therefore enable continuous monitoring of the functional quality of scanning.
  • Warnings and alarms enable conclusions concerning components affected by equipment failure, for example the light unit or signal amplitude.The electronic ID plate immediately displays all technical encoder parameters upon device switch-on. 

The subsequent electronics can independently configure the signal period or measuring step with the transmitted information. The EnDat 2.2. interface also enables the retransfer of information to the length gauge. 

Two company departments directly benefit from this added value:

  • Quality Assurance can determine the quality of measurements with this diagnostics information. 
  • Machine Maintenance is able to avoid unnecessary idle times during production thanks to the valuation numbers. 

The valuation numbers are dynamically created in a way similar to the maintenance intervals of modern cars according to their running conditions. The encoder detects if a light source is aging or contaminated, for example. The additional information can be provided by all HEIDENHAIN evaluation electronics, and supplementary software or hardware modules are not needed. The following evaluation units are available for the purpose: 

  • the ND 287 for single or dual-axis measuring tasks
  • the ND 2100G GAGE-CHEK with up to eight measuring channels
  • the MSE 1000 with up to 250 measuring channels 

These evaluation electronics support the EnDat 2.2 interface and ensure all applications benefit from this diagnosis functionality. The MSE 1000 also features additional diagnostics for analog interfaces, e.g. for testing the signal amplitude.

The absolute scanning of HEIDENHAIN ACANTO length gauges immediately delivers a measured value without the need for a reference run. The length gauges with a measuring range of 12 mm or 30 mm repeatedly measure a new absolute value. Measuring errors from excessive plunger speeds, caused by bounce for example, belong to the past. Today’s HEIDENHAIN ACANTO length gauges are equipped now for future requirements. Evaluating the quality of measurements and the status information of the device provides added value for various departments in the company and helps to design production with greater efficiency.
