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 B1 serves as an input for the
auxiliary incremental encoder
(differential or single-ended).
Port B2 is used to output
differential buffered Auxiliary
Incremental Encoder signals.
For applications such as
Follower, ECAM, or Dual Loop.
Port B1 serves as an input for
Pulse & Direction commands
(differential or single-ended).
Port B2 is used to output
differential buffered Pulse &
Direction signals.
3.4.7 Auxiliary Feedback (FEEDBACK B)
When using one of the auxiliary feedback options, the relevant functionality of FEEDBACK B
ports are software selected for that option. Refer to the SimplIQ Command Reference Manual
for detailed information about FEEDBACK B setup.
3.4.7.1 Main Encoder Buffered Outputs or Emulated Encoder Outputs Option on
FEEDBACK B (YA[4]=4)
Through FEEDBACK B (Ports B1 and B2) the Cello can provide two simultaneous buffered main,
or emulated, encoder signals to other controllers or drives. This option can be used when:
 The Cello is used as a current amplifier to provide position data to the position
controller.
 The Cello is used in velocity mode, to provide position data to the position
controller.
 The Cello is used as a master in Follower or ECAM mode.
