When the position feedback is initialized at power-up or at any other time, a delay is included before
the information from the feedback device is used or any attempt is made to communicate with the
device. The minimum delays are shown in the table below. P1 Additional Power-up Delay (1x.049)
defines an additional delay that is added to the minimum delay.

If P1 Linear Feedback Select (1x.051) = 0 then the drive P1 position feedback interface is
configured to operate with a rotary position feedback device. P1 Rotary Turns Bits (1x.033) and P1
Rotary Lines Per Revolution (1x.034) should be used to set up the position feedback interface.
If P1 Linear Feedback Select (1x.051) = 1 then the position feedback interface is configured to
operate with a linear position feedback device. P1 Linear Comms Pitch (1x.052) and P1 Linear Line
Pitch (1x.053) should be used to set up the position feedback interface.
* BiSS is not currently supported.
