Table 5-2 Supported feedback devices on the P2 position interface
Quadrature incremental encoders with or without marker pulse
Frequency and direction incremental encoders with or without marker pulse
Forward / reverse incremental encoders with or without marker pulse
EnDat communication only encoders
SSI encoders (Gray code or binary)
BiSS communication only encoders (not currently supported)
Table 5-3 shows the possible combinations of position feedback device types connected to the P1
and P2 position interfaces and the availability of the encoder simulation output.

The priority of the position feedback interfaces and the encoder simulation output on the 15-way D-
type is assigned in the following order from the highest priority to the lowest.
• P1 position interface (highest)
• Encoder simulation output
• P2 position interface (lowest)
* BiSS is not currently supported.
