3.10.2 Auxiliary Feedback – Emulated, Differential Buffered
Encoder Output Option (YA[4]=4)
The Auxiliary Feedback's B2 port can provide emulated encoder signals to other
controllers or drives. This option can be used when:
A Resolver or Analog Encoder is used as a Main Feedback device.
The Whistle is used as a current amplifier to provide
position data to the position controller.
The Whistle is used in velocity mode, to provide
position data to the position controller.
The Whistle is used as a master in Follower or ECAM mode.
Below are the signals on the Auxiliary Feedback ports when the Whistle Auxiliary Feedback
port is set up for emulated output of the Main Feedback device (Resolver or Analog
Incremental Encoder only).
The Auxiliary Feedback on the Duo has a 16-pin Molex Header plug.
