4.2 Power connections

The NextMove ST can accept AC or DC power supplies, and has connections for separate drive and logic supplies. However, the NextMove ST can operate from a single combined supply if necessary.

Supply	Recommended	Supply voltage	Power

4.2.1 Operation using combined drive and logic supply

To operate the NextMove ST using a combined drive and logic supply, it is necessary to connect links between the power input connections as shown in Figure 2. The drive and logic supply inputs have independent bridge rectifiers so polarity is not important. The NextMove ST creates its own ±12V and +5V supplies for the control card and internal circuitry by deriving power from the drive supply.

The regulated ±12V and +5V supplies are made available on the power out connector, for use with low power external circuitry, such as input potentiometers. Current demand must not exceed 10mA from the ±12V supply and 200mA from the 5V supply.
