Applications
Any application where two Feedbacks are
used by the drive.
The Auxiliary Feedback port serves as an
input for the Auxiliary incremental encoder.
For applications such as Follower, ECAM, or
Dual Loop.
Any application where two Feedbacks are
used by the drive.
The Auxiliary Feedback port serves as an input
for Pulse & Direction Commands.
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 DC Whistle is used as a current amplifier to provide position data to the position
controller.
• The DC Whistle is used in velocity mode, to provide position data to the position controller.
• The DC 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 DC Whistle has a 16-pin Molex Header plug.
