3.5.6 Main and Auxiliary Feedback Combinations
The Main Feedback is always used in motion control devices whereas Auxiliary Feedback is often,
but not always used. The Auxiliary Feedback port “FEEDBACK B” (J2) can be used in
combination with the Main Feedback port, “FEEDBACK A” (J3). Feedback B can be set by
software as follows:

Typical
Applications
 Any application where the
main encoder is used, not
only for the drive, but also
for other purposes such as
position controllers and/or
other drives.
‘
Analog Encoder
applications where
position data is required in
the Encoder’s quadrature
format.
’ Resolver applications
where position data is
required in the Encoder’s
quadrature format.
Any application where two
feedbacks are used by the
drive.
Port B serves as an input for
the auxiliary incremental
encoder (differential or single-
ended).
For applications such as
Follower, ECAM, or Dual
Loop.
Port B serves as an input for
Pulse & Direction
commands (differential or
single-ended).
