Elmo 1.1, Guitar Digital Servo Drive 3.9 Main Feedback

3.9 Main Feedback
The Main Feedback port is used to transfer feedback data from the motor to the drive.
The Guitar can accept any one the following devices as a main feedback mechanism:
 Increment al encoder only
 Incremental encoder with digital Hall sensors
 Digital Hall sensors only
 Increment al Analog (Sine/Cosine) encoder (option)
 Resolver (option)
 Tachometer (opt ion)
 Potentiometer (option)
 Absolute Encoder (optional on the solo board)
Incremental Encoder Interpolated Analog Encoder Resolver Tachometer and Potentiometer
