P2 Comms Baud Rate (2x.037) defines the baud rate used for encoder communications.
Restrictions are applied to the baud rate for different feedback devices, and so the baud rate may
be different to the parameter value.
P2 Device type (2x.038) : EnDat, BiSS*, SSI
Any baud rate that is within the range specified for the encoder may be used. The line delay is
measured during Initialization, and used to compensate this delay during communications with the
encoder. Therefore there is no timing based restriction on the length of the cable between the
position feedback interface and the encoder. However, care should be taken to ensure that the
wiring arrangement and the type of cable used are suitable for the selected baud rate and the
distance between the position interface and the encoder. See P2 Low Speed Update Rate Active
(2x.063) for more details on timing restrictions related to the drive sample times.
P2 Device type (2x.038) : Any other device
P2 Comms Baud Rate (2x.037) has no effect.
* BiSS is not currently supported.
