Control Loop Feedbacks

The default source for Axis 1 is Feedback 1, and for Axis 2 is Feedback 2. This means only SFD3 and HIPERFACE DSL are supported by default. To use other feedbacks, AXIS#.IL.FBSOURCE must be changed to 3 for Feedback 3 and Feedback 3 must be setup for the desired feedback or SFA.

Each axis has a set of control loop feedback sources:

AXIS#.IL.FBSOURCE is the current loop feedback source, sometimes referred to as the commutation feedback source.
AXIS#.VL.FBSOURCE is the velocity loop feedback source.
AXIS#.PL.FBSOURCE is the position loop feedback source.

AXIS#.OPMODE determines which control loops are active, and therefore which feedback sources are used.

The default control loop feedback sources corresponds to the axis. For Axis 1, the feedback sources default to Feedback 1. For Axis 2, the feedback sources default to Feedback 2.

Two-wire feedbacks (SFD3 and HIPERFACE DSL) and feedbacks connected via SFA can be used with the default feedback sources. When other feedback connections, such as Feedback 3, are used as control loop sources, the FBSOURCE parameters must be set accordingly.
