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.
NOTE
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.
