GENERAL DESCRIPTIONEXCITATION MODE SELECT 
The DPF73003 Step Motor Driver Pack is designed to
operate three axes of 4-phase step motors rated at 1 - 7
amps/phase. These Driver Packs contain a three-axis step
motor driver,  a 500 Watt power supply, and a cooling fan.
Outstanding motor performance is provided by means of a
bilevel drive technique.
BILEVEL DRIVE
The basic function of a step motor driver is to control the
motor winding currents.  Motor performance is determined
by how fast the driver can increase and decrease theDual Clock operation. Terminal 5 can be configured as the
winding currents. A rapid rise in winding current is achieved
by applying a high voltage directly to a motor.  This rapid
rise of current is also referred to as the kick or operating
current.  When a desired current level is reached, a low
voltage is applied to maintain a suitable holding current
level.  When a motor winding is turned off, a rapid decrease
in winding current is achieved by routing the energy in the
collapsing field back to the power supply through a high
voltage path.  The high voltage supply furnishes the energy
necessary to maintain motor output torque at high step rates
thus providing high mechanical power output.  The low
voltage supply provides much of the current needed at low
step rates and all of the holding current.  
Bilevel drivers do not use high frequency switching
techniques as chopper drivers do.  Consequently, they do
not create the EMI, RFI, and motor heating problems that
are associated with chopper drivers.Users have a choice of dual-phase, full-step operation or half-step
operation. Dual-phase, full-step operation occurs by energizing two
phases at a time, rotating a typical motor 1.8 degrees per step.
Half-step operation occurs by alternately energizing one, and then
two, phases at  a time, rotating the motor 0.9 degrees per step.
Full-step operation is only suggested for applications that
specifically require that mode, such as when retrofitting existing
full-step systems.
STEP AND  DIRECTION CONTROL
The DPF73003 has two clock options:  Clock and Direction, or
Direction Input or CCW Input by placing jumper JP2, JP8, and
JP14 in the appropriate position (see Table 1).  Pulses applied to
the Clock input cause the motor to step in the clockwise direction
if the Direction Input is a logic 1 or the counterclockwise direction
if the Direction Input is a logic 0.  Pulses applied to the CCW
Input cause the motor to step in the counterclockwise direction.
Either positive or negative going pulses may be selected by setting
JP1, JP7, and JP13 to the appropriate position (See Table 1).
MOTOR ON/OFF INPUT
The motor on/off input allows for de-energizing a motor without
disturbing the positioning logic.  After re-energizing  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.

TABLE 1: JUMPER SETTINGS 
FIGURE 2: BL73 JUMPER LOCATIONS ADJUSTING KICK CURRENTSPECIFICATIONS
The kick (or operating) current level is the desired phase
current level that the high voltage provides each time a step
is taken.  The high voltage is turned off when this level is
reached.  The kick current level should be set to
approximately 1.4 times the rated phase current.  For
example, a motor rated at 5 amps/phase should be kicked
to 7 amps (5 x 1.4 = 7).  Table 2 shows various kick current
levels for corresponding phase currents. 
WARNING:  The kick current level must be set before
operating a motor.

and 7 Amps per phase maximum standstill current.  Motor
phase  ratings of 1.0 Amp minimum are required to meet the
minimum kick level.

Note:  DPF73003 Driver Packs are available with 250VAC
power input upon request. Order Part Number

Operating Temperature : 0 to 60 degrees C
The DPF73003 contains an internal fan to create airflow
through the unit.  Heating considerations should include:
location where unit is mounted, the duty cycle of operation,
ambient temperature and air flow.  Care should be taken so
that no point on the chassis exceeds 60 degrees Celsius.

MOTOR CONNECTIONS 
Figures 3 and 4 are hookup diagrams for typical DPF73003
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 50 feet, consult the factory.
