April 2012 L010125 What is a Step Motor Driver? A step motor driver is a device that takes input signals (usually Clock and Direction) and translates this information into phase currents in the motor. Each time the step motor driver receives a pulse, the step motor moves one step. If the driver receives 200 pulses, the motor moves 200 steps. The motor steps at the same frequency as the clock pulses. General Description The BLD75 is a step motor driver that can drive motors rated from 1 to 7 amps/...

April 2012 L010125 Clock Modes The BLD75 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 (Termi- nal 6) cause the motor to step. The direction of the motor is determined by the logic level of the Direction input (Terminal 5). Jumper JP2 must be in the...

April 2012 L010125 Jumper Functions/Locations If a fault occurs, reset the fault by applying a logic “0” to the Reset Fault Input (pin 4) for at least 100ms or by cycling power off for at least 15 seconds. After resetting, try to run the motor again. If the driver continues to fault, check the conditions listed in the troubleshooting section on page 11. Adjusting Kick Current By following the instructions on the cover, use a small screwdriver to adjust the potentiometer. Line up the potentiometer’s...

April 2012 L010125 Motor Connections Figure 5 is a hookup diagram for typical BLD75 driver applications. The input signal connection must be separate from motor connections and all other possible sources of interference. IMPORTANT NOTE: When the motor cable between the driver and the step motor extends beyond 25 feet, consult the factory. Wiring Diagram The wiring diagram in Figure 5 shows the BLD75 with the AA2791 Transformer. For wiring with the AA2793 Transformer, refer to fi gure 9 Power Supply...
