Page 3: Clock Modes
Clock Modes The BLD72 has two clock options: Clock and Direction, or Dual Clock operation. Jumper JP2 is used to select the clock option. Basically JP2 selects Terminal 5 as either the Direction input or the CCW input. With the Clock and Direction option (most common option), clock pulses applied to the Clock input (Ter- minal 6) cause the motor to step. -

Line up the potentiometer’s arrow to the number corresponding to the motors rated current (amps/phase). Example 1: 23D104 Motor, Set to 2.0A. -
Page 5: Wiring Diagram
GENERATOR 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. - Page 6 Transformer Drawings .800 MAX 1.500 1.450 MAX Note: The AA2793 transformer is the same physical size as the AA2791, but it has two sets of second- ary windings (to power two drivers) and a dual primary winding for 115/230V operation.
