3.4.5 Main Feedback Cable (Feedback A)
The main feedback cable is used to transfer feedback data from the motor to the drive.
The Tuba accepts the following as a main feedback mechanism:
 Increment al encoder only
 Incremental encoder with digital Hall sensors
 Digital Hall sensors only
 Interpolated Analog (Sine/Cosine) encoder (option)
 Resolver (option)
 Tachometer and Pot entiomet er
 Absol ute encod er
FEEDBACK A on the front of the Tuba has a 15-pin D-sub socket. Connect the Main Feedback
cable from the motor to FEEDBACK A using a 15-pin, D-Sub plug with a metal housing.
When assembling the Main Feedback cable, follow the instructions in Section 3.4.4 (Feedback
and Control Cable Assemblies).
