EnDAT2.2 Encoder Status and Error

Information

For the EnDAT2.2 encoder, Gate3[i].Chan[j].SerialEncDataB is set as follows.

31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8

Error

Bits 29, 30, and 31 represent the communication error bits, which are set as follows, respectively.

Bit 29: Error bit (For the meaning of this bit, refer to the encoder manual.)

Bit 30: CRC error

Bit 31: Timeout error

If a CRC error occurs frequently due to noise, etc. when you monitor each communications error bit

with a user program, it is necessary to modify the program so that only three consecutive occurrences

of the error are regarded as an error. If the CRC error still occurs frequently even after such a modifi-

cation of the program, it is assumed that the influence of noise is significant. In this case, reduce the

noise level by enhancing the shielding and grounding effects or changing the wiring.

Bits 0 to 7 are the upper 8 bits of position data from the encoder.
