Short Description Actual Position from Feedback Device

Description

The PFB command returns the actual value of the position (from the position control loop feedback). The unit for the position value depends on the PGEARI, PGEARO and PRBASE settings.

PFB = Position * PGEARI / PGEARO
whereby:
Position = position value in increments, 1048576/turn for PRBASE=20, 65536/turn for PRBASE=16
PGEARI, PGEARO - resolution of position control loop

Note: If the resolution is set to 1 (PGEARI=PGEARO) then the PFB command provides internal units (counts).

If the position information of an external encoder is evaluated (EXTPOS=1,2,3), then this information can be displayed by using the PFB0 command.
