7.4.3 P2 position interface
This section shows the parameter settings which must be made to use each of the compatible feedback device types with the P2 position interface on
the drive. For more information on the parameters listed here please refer to the Parameter Reference Guide. If the position feedback device
connected to the P2 position interface is required to be used for motor control feedback then Pr 03.026 will need to be set to P2 Drive (1).
Table 7-4 Parameters required for feedback device set-up on the P2 position interface
 Information required to be entered by the user.
Parameter can be set-up automatically by the drive through auto-configuration. Parameter must be set by the user if auto-configuration is
disabled (i.e. Pr 03.041 = Disabled (0)).
The P2 position interface does not have its own independent power supply output. Therefore, any position feedback device connected to the P2
position interface must either share the P1 power supply output on pin 13 of the 15-way D-type, or be supplied from an external source.
The termination resistors are always enabled on the P2 position interface. Wire break detection is not available when using AB, FD or FR position
feedback device types on the P2 position interface.
Table 7-4 shows a summary of the parameters required to set-up each feedback device. More detailed information follows.
