Having had a quick check of the manual, the drive should come as default set by software (I can't see the exact value listsed anywhere), however you can quickly change it by using the DIP switches.

So you can either connect the drive up to a computer and configure it through the ProTuner software, or just flick the DIP switches to acheive what you want (page 7 of the manual at http://www.leadshine.com/UploadFile/Down/AM882m.pdf shows the settings).
