EnDat (4) for an EnDat communications only encoder
BiSS* (6) for a BiSS communication only encoder
Auto-configuration is enabled as default and automatically sets up the
following parameters:
Rotary Turns Bits (2x.033) (Not BiSS*)
Rotary Lines Per Revolution (2x.034) (Not BiSS*)
Comms Bits (2x.035) (Not BiSS*)
Comms Baud Rate (2x.037) (BiSS* Only)
Recovery Time (2x.060) = 13 μs (BiSS* only)
Calculation Time (2x.061) = 5 μs (BiSS* only)
These parameters can be entered manually when Pr 2x.041 is set to Disabled
(0).
