Provided the set-up parameters for the position feedback device connected to the drive P2 position
interface are correct P2 Speed Feedback (2x.027) shows the speed derived from the feedback.
The speed is given in mm/s if P2 Linear Feedback Select (2x.051) = 1 and Linear Speed Select
(01.055) on the drive = 1, otherwise it is given in rpm.

P2 Revolution/Pole Pitch Counter (2x.028) , P2 Position (2x.029) and P2 Fine Position (2x.030)
combined give the encoder position with a resolution of 1/232 of a revolution/pole pitch as a 48 bit
number. If a rotary position feedback device is being used (P2 Linear Feedback Select (2x.051) =
0) then these quantities relate directly to the rotary position of the feedback device. If a linear
feedback device is used then one revolution or pole pitch relates to the distance given by P2 Pole
Pitch (2x.055).
See P1 Revolution/Pole Pitch Counter (1x.028) for more information.
