SETTING THE MOVE DISTANCE 
The index count or move distance for the DPFHP451 can be accomplished by a number of methods.    The easiest way is 
to use the red switches labeled “Internal Index Number” on the unit; these switches are used by default.    External Count 
Modules may also be used.        These include the Click Pot Module, AA1748, the Thumbwheel Module, AA1760,    the BCD 
Input Module, AA2210, and the Quad Board, AA1754.    These modules set the distance of the move, but will allow for 
different variations in interfacing (see descriptions in next section). 
 
JUMPERS 
There are four jumpers on the Manual Preset Indexer board.   The first jumper, JP1, is used to set the debounce delay 
time for the JOG, HOME, and INDEX inputs.    When JP1 is in the “1-2 position, the debounce delay is approximately 12.5 
milliseconds.    When JP1 is in the “2-3 position, the debounce delay is approximately 0.3 milliseconds.    The active low 
signal on these inputs must be wider than the debounce delay time. 
 
To use an external Count Module, the INT/EXT input (pin 13) must be pulled low to a logic    “0.    The on-board switches 
will be ignored.    External Count Modules plug into either connector labeled “EXTERNAL COUNT MODULE 
CONNECTOR”(P1 or P2).    When only using one module for both FORWARD and REVERSE indexes, jumper JP2 must 
be in the “1-2 position. 
 
When using external Count Modules, it is possible to use one module for FORWARD indexing and another module for 
REVERSE indexing.    The connector on the side of the unit is the FORWARD count; the connector on the top (of front 
face) is the REVERSE count.    When using two modules for different FORWARD and REVERSE indexes
, jumper JP2 
must be in the “2-3 position.

COUNT INPUT BOARDS 
All of the Count Input Boards or Modules set the number of steps the motor will move when an Index is initiated, but each 
Module allows for a different variation in interfacing. 
 
AA1748 - CLICK POT MODULE 
A CLICK POT module consists of 10 position (0 - 9) digital pots mounted on a printed circuit board.    One pot is used per 
each decade (digit).    These units are available in 2, 4, or 6 decades.    The user dials in the step count on the pots.    Any 
time the motor is indexed, it will move the number of steps set on the pots.    One module is required per axis.    The module 
is connected to the Manual Preset Indexer via a supplied 5 lead cable. 
 
 
 
 
AA1760 - THUMBWHEEL SWITCH MODULE 
These thumbwheel switches provide an attractive way to input a step count.    The user dials in the desired count on the 
thumbwheels, which can be mounted on an enclosure face.    The module is available in 3, 4, 5, or 6 decades.    The 
module is connected via a supplied 5-lead cable. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
AA1754 - QUAD BOARD COUNTER 
The quad board module is a 4-bank version of the clickpot module with each bank having 6 decades.    The user can dial

in four different move lengths and then select any one of them as desired.    The module is connected to the indexer via a 
supplied 5-lead cable.

TABLE 9 
 
The selection of the switch banks is done by switching select lines 1 and 2 on connector P3.    The select lines are low 
true meaning that if a select line is pulled low (to 0Vdc), it is recognized as being on or true.    When a select line is not 
pulled low it is internally pulled up to +5Vdc and is off or false.    The bank select lines must be set at least 1 
millisecond before the Index command is given.    The select lines must remain in the set state until the index is complete.   
Once the move is finished, the select lines may be changed as needed.

Select line #4 is only used if additional count input devices are daisychained to the expansion connector (P2).    If select 
line #4 is low, that quad board is ignored and the count input device connected to the P2 expansion connector is read.   
This allows multiple quad boards to be used together.    The daisychained count input device does not have to be a quad 
board; it could be a thumbwheel switch or click pot module.

AA2210 BCD COUNTER MODULE 
The AA2210 BCD counter interface module enables the user to select any move length from 0 to 999,999 steps using a 
standard PLC (programmable logic controller).      Selecting the proper inputs creates a count value in steps, resulting in a 
move distance.    The module is connected to the indexer via a supplied 5-lead cable. 
 
Note:    All Inputs are active low (0-0.8Vdc).    All unused inputs may be ignored since they are pulled up. 
 
Example:    For a move distance of 1234 steps the following inputs should be pulled low. 
 
1s Decade: Bit 4 (TB1, pin 4) 
10s Decade: Bit 1 and 2 (TB2, pin 2 and 3) 
100s Decade: Bit 2 (TB1, pin 7) 
1000s Decade: Bit 1 (TB2, pin 6) 
 
All Other inputs must be open or high (3.5-5Vdc).

MODE SELECT 
When programmed as Mode Select Input (set by JP2), this terminal is internally pulled up to +5VDC through a 10k ohm 
resistor.    When a logic 1 (or no connection) is applied, the motor will operate in halfstep mode.    When a logic 0 is 
applied, the motor will operate in fullstep mode.   
 
MOTOR ON/OFF INPUT 
This terminal is internally pulled up to +5VDC through a 10k ohm resistor.    When a logic 1 (or no connection) is applied, 
the driver phase outputs are enabled and the motor is energized.    When a logic 0 is applied, the driver phase outputs 
are disabled and the motor is de-energized. 
 
MOTOR PHASE OUTPUTS: (Terminals 1,2,13,14)     
These outputs can sink a peak of 15 Amperes or sink 10 Amperes continuously and stand-off 250 VDC maximum. 
 
MOTOR COMMON OUTPUTS: (Terminals 3,12) 
These outputs can source a peak current of 15 Amperes, or source 10 Amperes continuously. 
 
AMBIENT TEMPERATURE: 0 to 50 degrees Celsius.
