How do I connect an Oriental Motor driver to the 7334 controller?

[football]

We plan simple one-axis control. We have a stepper motor, driver (Oriental Motor AS series), and a PCI 7334 controller. I want to connect the driver to the 7334 controller without a UMI, but wiring isn't understood because I'm totally new in motion control. How can I connect the two? I'm afraid that misconnection might cause damage to the device. Any help would be greatly appreciated.

Take a look at the diagram on page B-55 in the manual. There are only three signals that you absolutely must connect; "Pulse Signal (CW)", "Rotation Direction (CCW)", and "All Windings Off". Connect the CW/CCW lines to their respective lines on the controller and connect the "All Windings Off" to the Inhibit line on the contoller, exactly as shown in this diagram. The controller and drive will support both CW/CCW and Step/Dir signaling, explained under the Pulse Input section on B-57. It does not matter which you choose. Just make sure they are set the same for both devices.

For closed loop control, you will also need to connect the encoder feedback from the drive to the controller. Use the wiring scheme shown for the open collector outputs (ASG1, BSG1). The
line driver outputs would probably also work, but I would recommend using ASG1 and BSG1 instead.

This should be all you need to get up and running.

Thank you, Brent R.
Your direction is very helpful, but there still are some points I cannot understand.

1 The UMI is not available for our system at present. Do I need a special terminal block between the 7344 controller and the motor driver?

2 According to the document shown at the support page(http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/c8f375d35d50836786256c560051b459?OpenDocument), I think the wiring is different from what you told me above and that it is necessary to connect pull-up resistors. Which connection is right for our system?
