Table 4-18 Availability of the P2 position feedback interface and 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)
For example, if an AB Servo type position feedback device is selected for use on the P1 position interface, then both the encoder simulation output
and the P2 position interface will not be available as this device uses all connections of the 15-way D-type connector. Also, if an AB type position
feedback device is selected for use on the P1 position interface and Pr 03.085 is set to a valid source for the encoder simulation output, then the P2
position interface will not be available.
Depending on the device type used on the P1 position interface, the encoder simulation output may not be able support a marker pulse output (e.g.
SC EnDat or SC SSI device types). Pr 03.086 shows the status of the encoder simulation output indicating whether the output is disabled, no marker
pulse is available or full encoder simulation is available.
When using the P1 and P2 position interfaces and the encoder simulation output together, the P2 position interface uses alternative connections on
the 15-way D-type connector. Pr 03.172 shows the status of the P2 position interface and indicates if alternative connections are being used for the
P2 position interface.
