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