Thought I'd give a more detailed explanation...

Here's the motor datasheet:

http://www.stepper-drives.co.uk/down...H156-4208B.pdf

It say your motors draw 6 amps in bipolar parallel, and your drivers do 5.6A max, so near enough. Bipolar parallel is generally the best...
So that means you need to connect each *phase* in parallel, then connect that to the drivers. i.e.:

Motor --> Driver

Red --> A+
Blue --> A+
Black --> A-
Yellow -->A-

White -->B
Brown -->B-
Orange -->B+
Green -->B+

Now we need to set the driver to 5.6 amps. It says in the table on the datasheet switches 1,2,3 should all be off for 5.6A.
Similarly you probably want 1/8 microstepping, which the other table says is switches 5,7,8 on and 6 off.
Switch 4 off since I doubt you need the full holding torque when stationary.

Hope that helps.
