3.9 Main Feedback
The Main Feedback port is used to transfer Feedback data from the motor to the drive.
The Duo accepts the following as a
Main Feedback mechanism:
ƒ
Incremental encoder only
ƒ Incremental encoder with digital hall
sensors
ƒ Digital hall sensors only
ƒ Incremental analog (sine/cosine)
encoder (option)
ƒ Resolver (option)
ƒ Tachometer and potentiometer
(option)
ƒ Analog Halls
The Main Feedback port on the Duo has a 12-pin Molex Header plug.
