Hi,
I have a Etsun E21 Press brake control and I wish to connect two servo motors to it however I am new to this and don't understand how the controller connects to the servo drive as the all the drives I have seen the encoder plugs into the drive not the controller as this one does.
The control has a series of outputs to connect to relays to drive the motors ( ie Direction, In position X- X+ Y- Y+ X++ Y++ etc). How do you connect this to a AC or DC Servo motor. I have done all the mechanical work and I am ready to buy some motors but came to a halt due to my lack of knowledge on the subject.
Any advise would be most appreciated.

Adrian.

Below is the pin outs on the output terminal to the relays to control the motors.
