integrator is large enough to guarantee that the position controller will operate with a position error within the range -32,768 revolutions to +32,767
revolutions before rolling over. The position error is displayed in Pr 13.01 , Pr 13.02 and Pr 13.03 . Pr 13.01 shows the turns error, Pr 13.02 shows the
error within a revolution in 1/2
16
counts per revolution units and Pr 13.03 shows the fine position error in 1/2
32
counts per revolution units. These
values are both positive and negative and so they can be used to show the following error with different levels of resolution.
For orientation mode the error between the orientation position and the position feedback source is shown in Pr 13.02 .
slots. The reference can also be taken from the local reference parameters. If the reference and feedback sources are the same the position
controller cannot be enabled. If a Solutions Module slot is selected as a source, but the module is not a position feedback category Solutions Module
the position controller cannot be enabled.
