Which status messages does an EnDat transmission have, or which status messages should be checked?
The EnDat interface distinguishes between the following status messages: Error message: An error message is set if there is a malfunction in the encoder that could be causing incorrect position values. Depending on the mode command used for position value transmission, F1, or F1 and F2 are transmitted (see also EnDat specification). Cyclic Redundancy Check (CRC): In order to detect errors resulting from interference during data transmission, a 5-bit CRC code is assigned to every data word. The CRC code is generated by hardware in the encoder. The evaluation in the subsequent electronics can also be realized with the hardware. All one-bit errors in data transmission can be detected by means of the CRC. The detection of high-order data transmission errors depends on the data word length and the data contents. The error bit is included in the formation of the CRC code. EnDat error types I, II and III: Error type I: This error type indicates that the transmission from the subsequent electr
