The auxiliary encoder inputs on the servo are differential. The 'Tie' terminal should be jumpered to the A- and B- inputs when you're connected to a single-ended signal. You should also tie the servo's DC common (pin 14) to the AD's DC common even if you don't use the servo's 5VDC supply to power the AD's pulse output.
The CW/CCW mode means that a pulse train at the A terminal will command motion in one direction and a pulse train at the B terminal will command motion in the opposite direction. I repeat, I know nothing about the AD module, so in my ignorance I'm going to suggest that you make sure you're not outputting an A quad B signal from the AD module.
To make sure your configuration of the servo is correct, try connecting/disconnecting the servo's +5VDC to the A input to see if you can generate any motion. You may have to set a fairly high master/slave ratio to be able to observe much motion from a single pulse.
