INTRODUCTION
The DPF72452XCE Driver Pack contains two Bilevel Step Motor Drivers (BLD72), a Manual Preset
Indexer board, a Transformer, and a cooling fan. Figure 1 shows the general configuration and layout of
the DPF72452XCE Driver Pack. The Thumbwheel Switch is used to set the index (number of steps or
move distance) and the Manual switches and/or PLC are used to initiate indexing, homing or jogging.
The Manual Preset Indexer is ideal for applications which are repetitive and require accurate positioning.
Some areas where Manual Preset Indexers are commonly used are:
- Robotics
- Machine Control
- Packaging
- Assembly Automation
- Fluid Control and Mixing Systems
- Table Positioning Systems
- Photographic Controls
- Custom Motion Control
- Cut - to - Length

DESCRIPTION AND FUNCTION
MANUAL PRESET INDEXER BOARD
The Manual Preset Indexer board utilizes the PI45 Preset Indexer integrated circuit (I.C.). Functions
available are Home, Hard and Soft Limit inputs, two Homing modes, Jog/Run, Fast Jog and switch
selectable Base Speed, Maximum Speed, Acceleration/Deceleration.
This board includes the necessary buffering and other circuitry for the PI45 chip that makes indexing
easy. The board can be operated manually or with a Programmable Logic Controller (PLC) to index a
set of pulses determined by the internal count switches or an external count module, such as the
AA1760-5 or similar device.
Indexer board features include:
- Internal Index Count switches
- Pulse Rates up to 14,792 pulses per second
- CW and CCW Home, Hard, and Soft Limit inputs
- Adjustable Motion “Complete” output
- Motion “Busy” output
- Clock pulses and step direction outputs
- CW and CCW Index inputs
- CW and CCW Jog/Run and Fast Jog inputs
- Two “Go to Home Position” modes
- TTL-MOS Compatible
- Pulse and reset outputs and coincidence inputs for interfacing with a
- 2 to 6 decade thumbwheel, rotary switch assembly or similar device
MANUAL PRESET INDEXER TERMINAL (P1) DESCRIPTION
PIN  FUNCTIONDESCRIPTION
1  -HARD LIMITWhen active low, this signal instructs the step motor to
halt all motion in CCW direction.
2  +HARD LIMITSame as -HARD LIMIT except in CW direction.
3  -SOFT LIMIT When active low, this signal instructs the step motor to
ramp down to base speed and complete the move. Input
active during a -Index or -Home function.
4  +SOFT LIMIT Same as -SOFT LIMIT except in CW direction.
5  -HOME LIMITUsed in H0 Homing mode in conjunction with -Soft Limit.
Giving -Home command (active low) causes  motor  to
ramp to high speed in the CCW direction until -Soft Limit is
contacted. At contact, motor will decelerate to base speed
and run until the -Home Limit is contacted, at which time
the motor will stop. 
						

							#L0101477 6        June 2008 6 +HOME LIMITSame as -HOME LIMIT except in CW direction.
7 -JOG/RUN A low level on this line causes the step motor to take one
step in the CCW direction. Normally, the JOG/RUN inputs
are manipulated by external pushbutton switches. A single
depression of the switch causes a “jog” operation, while
holding the switch down for 0.5 seconds causes a “slow
run” condition. This command may be used with FAST to
perform a fast run at the base speed rate.
8 +JOG/RUN Same as -JOG/RUN except in CW direction.
9  -HOME A low level on this line instructs the step motor to move
to the home position via the CCW direction. (See HOME
SELECT)
10 +HOMESame as -HOME except in CW direction.
11 -INDEXWhen low, this signal causes the PI45 chip to read the
current motion parameters and number of steps from the
thumbwheel switches and command the motor to step the
indicated distance in the CCW direction. (See -SOFT
LIMIT). NOTE : If -SOFT LIMIT is encountered during an
Index, the motor will decelerate to base speed and com
plete the Index.
12 +INDEXSame as -INDEX, but commands a CW step motion.
section on Jumpers).
13 #INT/EXTThis input determines which set of switches will be used
for counting. A logic “1” or open selects the Internal Index
Count Number. A logic “0” selects the count of an external
counter module.
14 HOME SELECT This input selects the type of “Home” operation to perform:
When active low, H0 Homing Mode is selected. It is a
standard deceleration and stop on switch operation. In
essence, type H0 is a combination of the HOME and
SOFT limit commands. When active high, H1 Homing
Mode is selected. H1 is used for antibacklash protection. It
performs a decelerate, reverse, return off switch operation.
NOTE: the switch must remain closed during deceleration,
reverse, and return in H1 Mode.
15 FAST When active low, it is used in conjunction with JOG/RUN to
cause a fast run (base speed) operation in the specified
direction.
16 BUSYThis open collector switch output is ON when the motor
is moving. This output can sink 0.5A and stand off 40Vdc
maximum. A 10k ohm pullup resistor can be jumpered in 
						

							#L0101477 7        June 2008 place to provide TTL levels (see section on Jumpers).
17 CLOCKThis output is an open collector output, 15 microseconds
wide (minimum) that is the clock input for the motor driver.
It is buffered to assure adequate drive for an LS-TTL input.
This signal is internally connected to the driver.
18 0VDC Ground (0Vdc).
19 DIRECTIONClockwise (CW) motion causes this output to be active
high i.e. logic “1”. Counterclockwise motion causes this
output to be active low i.e. logic “0”. This output tells the
motor driver which direction to run. This signal is internally
connected to the driver.
20 COMPLETE This open collector switch output turns on after the
indexing cycle is executed. The pulse width (time that this
output is on) is adjustable from about 12ms to 120ms (see
Table). This output can sink 0.5A and stand off 40Vdc
maximum. A 10k ohm pullup resistor can be jumpered in
place to provide TTL levels. (see section on Jumpers).

BLD72 BILEVEL DRIVER
The BLD72 step motor driver employs a bilevel drive technique for highperformance operation of step
motors. The driver is designed to operate 4-phase, 6 or 8 lead step motors, providing high torque output
and higher startstop speeds. This driver is rated for output currents of 10 Amps/phase when
running and 7 Amps/phase at standstill. The BLD72 includes fault protection against shorted and open
motor wires. If any type of fault is detected, the driver will turn off current to the motor, and the Fault LED
will indicate which type of fault occurred.
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 the winding currents. A rapid rise in
winding current is achieved by applying a high voltage directly to a motor winding until a desired current
level is reached. Then a low voltage is applied to maintain a suitable holding current level. When a motor
winding is de-energized (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.
ADJUSTING THE KICK CURRENT
The kick 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. To obtain a proper setting, refer to the
silkscreen on the side of the unit and adjust the potentiometer to the rated phase current of the motor.
This internally sets the kick current 40% over the rated phase current.
WARNING: The kick current level must be set before operating a motor. BILEVEL DRIVE 
						

							#L0101477 9        June 2008 FAULT PROTECTION
There are three types of fault detection. When a fault is detected, the driver turns off the motor current
and the red Fault LED indicates which type of fault occurred. See the Troubleshooting section for more
information.

If the driver goes into a fault condition, the fault may be reset by turning the power OFF for at least 15
seconds or by pulling the RESET FAULT input (terminal 4) to a logic “0” for at least 100ms.
