4.2.2 Operation using separate drive and logic supplies

For improved noise immunity, the ±12V and +5V supplies used for the control card and internal circuitry can be derived from a separate logic supply. To operate the NextMove ST using separate drive and logic supplies, do not link power input connector pins. Connect power as shown in Figure 3.
