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 Falcon can provide two simultaneous buffered
main, or emulated, encoder signals to other controllers or drives. This option can be used
when:
• The Falcon is used as a current amplifier to provide position data to the position controller.
• The Falcon is used in velocity mode, to provide position data to the position controller.
• The Falcon is used as a master in Follower or ECAM mode.
