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 Tuba 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 Tuba can provide two simultaneous 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.
Below are the signals on the Auxiliary Feedback ports when set up to run as a buffered outputs
or emulated outputs of the main feedback (on FEEDBACK A):
