P1 Linear Comms And Line Pitch Units (1x.054) defines the units used by P1 Linear Comms Pitch
(1x.052) and P1 Linear Line Pitch (1x.053) in either millimeters or micro metres.

P1 Pole Pitch (1x.055) is used to define the distance equivalent to one pole for linear position
feedback devices. If the linear position feedback device is being used with a linear motor, then P1
Pole Pitch (1x.055) should be set to the pole pitch of the motor.

If P1 Feedback Reverse (1x.056) = 1 the position feedback is negated. This can be used to reverse
the direction of the position feedback.

The combination of P1 Revolution/Pole Pitch Counter (1x.028), P1 Position (1x.029) and P1 Fine
Position (1x.030) give the position feedback as a 48 bit value. This position cannot be read
atomically without locking the position feedback (P1 Feedback Lock (1x.050) = 1) and it cannot be
used directly by the Advanced Motion Controller.
It is useful to be able to create 32 bit position values that can be held by a single parameter as this
value can be accessed atomically and can be used directly by the Advanced Motion Controller.
