X20DS1928Description:
- EnDat 2.1 and EnDat 2.2 encoder interface
- Encoder input monitoring
- 5 VDC and GND for encoder supply
- NetTime timestamp: Position time
The module is equipped with an EnDat encoder interface. The module automatically detects whether an encoder is connected with EnDat 2.1 or EnDat 2.2. This module can be used to evaluate encoders installed in B&R servo motors as well as encoders for external axes (encoders that scan any machine movement). The input signals are monitored. This makes it possible to detect open or shorted lines as well as encoder supply failures.
