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 Tuba can provide two simultaneous
buffered main, or emulated, encoder signals to other controllers or drives. This option
can be used when:
buffered main, or emulated, encoder signals to other controllers or drives. This option
can be used when:
The Tuba is used as a current amplifier to provide position data to the position
controller.
The Tuba is used in velocity mode, to provide position data to the position controller.
The Tuba is used as a master in Follower or ECAM mode.
The Tuba is used as a master in Follower or ECAM mode.
Below are the signals on the Auxiliary Feedback ports when set up to run as a buffered

Pin Assignments
FEEDBACK B, on the front of the Tuba, has a 15-pin D-sub plug. Connect the Auxiliary
Feedback cable, from the controller or other device, to FEEDBACK B using a 15-pin D-Sub
socket with a metal housing. When assembling the Auxiliary Feedback cable, follow the
instructions in Section
