Rotary Lines Per Revolution (2x.034) should be used to set up the position feedback interface.
If P2 Linear Feedback Select (2x.051) = 1 then the position feedback interface is configured to
operate with a linear position feedback device. P2 Linear Comms Pitch (2x.052) and P2 Linear Line
Pitch (2x.053) should be used to set up the position feedback interface.

P2 Linear Comms Pitch (2x.052) is used to define the distance covered by the least significant bit
of the position information in a comms message from a linear encoder. The units used by this
parameter are defined by P2 Linear Comms And Line Pitch Units (2x.054).
P2 Device type (2x.038): Any other device
P2 Linear Comms Pitch (2x.052) has no effect.

P2 Linear Line Pitch (2x.053) only has any effect if the position feedback interface is being used
with a linear device (i.e. P2 Linear Feedback Select (2x.051) = 1) and should be used to define the
distances listed below for each type of device. The units used by this parameter are defined by P2
Linear Comms And Line Pitch Units (2x.054).
P2 Device type (2x.038): AB
P2 Linear Line Pitch (2x.053) should be set to the distance covered by one line period on the
encoder.
P2 Device type (2x.038): FD, FR
P2 Linear Line Pitch (2x.053) should be set to the distance covered by two line periods on the
encoder.
P2 Device type (2x.038): Any other device
P2 Linear Line Pitch (2x.053) has no effect.
