Compatibility
The extended interface version EnDat 2.2 is compatible with the previous version 2.1 in terms of communication, command sets and time conditions, but offers significant advantages. For example, it is possible to send additional information with the position value without having to start a separate query. To this end the interface protocol has been extended and the time conditions optimized as follows:
- Increased clock frequency (CLOCK)
- Optimized computing time (determination of position value within 5 µs)
- Minimize recovery time (1.25 to 3.75 μs)
- Extended voltage supply range (UP = 3.6 to 5.25 V or 3.6 to 14 V at the encoder)
The following figure shows the command set of the extended interface version EnDat 2.2:
