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.

Clock Modes
The BLHV 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...

Motor ON/OFF Input
The motor on/off input allows de-energizing a motor without disturbing the positioning logic.  After reen-
ergizing the motor, a routine can continue.  This reduces motor heating and conserves power, especially 
in applications where motors are stopped for long periods and no holding torque is required.  If holding 
torque is required (such as when lifting a load vertically), then the motor must stay energized.

Power Supply Requirements
The DPD72001 and DPD72002 are both powered by an AC line voltage of 110VAC.  The X250 version is 
capable of line voltages ranging from 90-265VAC.  The following fi gure shows the various line voltages.

Specifi cations
Control Inputs (All): (Terminals 5, 6, 8, 9)
TTL - Compatible
Logic “0” = 0-0.8V
Logic “1” = 3.5 to 5.0V
Fault Reset: (Terminal 4)
Pulled up to +5VDC through a 10k Ohm
Logic “1” (open) - Driver enabled and Fault detection enabled
Logic “0” - Reset a Fault condition (driver is disabled when this input is low).  This input must be held low 
for at least 100ms.
Clock Inputs: (Terminals 5 and 6)
Pulse required; 15 microseconds minimum.  The clock input is pulled up/down...

Troubleshooting
If a Fault occurs, reset the Fault by applying a logic “0” to the Reset Fault Input (terminal 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 faults again then check the conditions listed below.
Is the LED Blinking Slowly? (once a second)
This indicates that the motor has a phase shorted or there is a short in the motor cable or wiring.  Check 
the motor and the wiring for shorts....
