Motor Connections

Figure 5 is a hookup diagram for typical BLD72 driver applications. Wiring connected to inputs must be separated from motor connections and all other possible sources of interference.

IMPORTANT NOTE: When the wiring from the driver to the step motor extends beyond 25 feet, consult the factory.

Wiring Diagram

The wiring diagram in Figure 5 shows the BLD72 with the AA2791 Transformer. For wiring with the AA2793 Transformer, refer to Figure 9.

Power Supply Requirements

The BLD72 must be powered by a recommended Anaheim Automation transformer. The AA2791 trans- former and the AA2793 transformer are the most commonly used and are both rated for 300VA. These transformers have a high voltage winding, a low voltage winding, and a logic voltage winding. The AA2793 has two high voltage windings and two low voltage windings for powering two BLD72’s. The high voltage winding (yellow) and low voltage winding (red) plug into the quick disconnects on the back of the BLD72 (see hookup diagram in Figure 5). The logic voltage winding (orange) is used to power up optional control- lers. When using one of these transformers, the nominal low-voltage is 5.0 volts and the nominal high- voltage is 60V. The transformer voltages are shown in Figures 7 and 8; the physical dimensions are shown in Figure 6. For other transformers, contact the factory.
