EEO - Analog control position loop
In an analog control position loop, feedback position is reading using an external encoder, that is mounted at rear side of servo motor, the servo motor shaft is extend out of servo motor
Encoder is leine linde brand part number 51841501 RSI 503, the controller is connected over rs25 port to external encoder, so pulse voltage is supplied by controller at 5 DC TTL, see illustration, and wiring attached file pdf
ACTUAL LOOP POSITION
We are going to replace servo motor and amplifier, i want to review if we can provide encoder signal to axis controller from AKD (E.E.O.), if this case is possible,
How can i make that connection between axis controller and AKD x9 port??
IS IT POSSIBLE TO SEND EMULATED ENCODER OUTPUT FROM AKD’S X9 PORT TO AXIS CONTROLLER INSTEAD OF EXTERNAL ENCODER?

You will connect the A, B and Z signals as listed on the controller. You should also connect the ground "5 volt return" of the controller to Pin 3 GND on the X9 connector. This will put the controller and the AKD EEO output signals at same reference point. Sometimes on the older controllers you have to also add terminating resistors across A, /A, B, /B and Z, /Z channels at the controller inputs to lower the impedance of the input circuit of the controller. The terminating resistors normally range from 240 to 150 ohms.
Yes, you can take the AKD drive's EEO from X9 to the controller for position feedback and the encoder from the motor to the AKD for the primary feedback on X10. Due to the encoder not having hall sensors or data communication channels, the AKD drive will have to run a wake and shake routine to figure out the commutation alignment of the motor every time the +24 volt logic is cycled on the AKD drive.
