4 FAULT RESET If this input is momentarily pulled low after a fault condition
occurs, then the fault is reset and the driver can run again.
5 DIRECTION This input is the direction control input. It is internally
connected to the Direction control output of the Manual
Preset Indexer. A logic “1” selects CW(+) direction. A logic
“0” selects CCW (- ) direction.
6 CLOCK IN A negative going pulse on this input causes the motor to
step. The Clock output of the Manual Preset Indexer is
internally connected to this input.
7 0VDC This 0Vdc is internally connected to the 0Vdc on the
Manual Preset Indexer.
8 HS/FS This is the excitation mode select input. A logic “1” selects
HALF-STEP excitation. A logic “0” selects dual phase
FULL-STEP excitation.
9 ON/OFFThis input may be used to turn off the motor current while
standing still. This will reduce heating in the driver and
motor. The motor is energized when this input is a logic “1”.
The motor is de-energized when this input is a logic “0”.

USING THE MANUAL PRESET INDEXER
SELECTING MOTION PARAMETERS
                Figure 5: Velocty Profile
The velocity profile (motion speed and acceleration) is determined by the four green switches; the Base
Speed, Max Speed, Acceleration/Deceleration, and Factor. Figure 5 shows a typical velocity profile of a
step motor.
BASE SPEED
This is the speed at which the motor starts to run. There are 256 choices of Base Speeds as shown in
the Table 3. They range from 2 steps/second to 3,611 steps/second.
MAX SPEED
As shown in Table 2, there are 256 choices available ranging from 163 steps/second to 14792 steps/
second.
ACCELERATION/DECELERATION
The step motor starts to accelerate after taking 4 steps at the base speed and continues until it reaches
the selected maximum speed taking the number of steps set by A/D at each speed in the internally
generated ramp table. A/D=0 is no acceleration (run at BASE speed only), A/D=1 is the fastest (mini-
mum ramp time), and A/D=F is the slowest (maximum ramp time). The step motor starts to decelerate
at the calculated point and continues until it reaches the selected base speed and stops.
FACTOR
The F switch should be set first because it directly affects the Base and Max speed. Table 1 lists the
maximum obtainable stepping rates for all F switch settings with the maximum speed F.

							#L0101477 14        June 2008 EXAMPLE :
Assume that the motor is to run at a Max Speed of 4500 steps/second. It can be seen from the table
above that this speed can only be obtained with the F switch setting of 0 through 4. Any of these switch
settings could provide speeds in excess of 4500 steps/second. The ‘rule of thumb’ is to always chose
the highest F switch setting that will provide the desired Max Speed, and also give the widest range for
Base Speeds. In this example, F with a switch setting of 4 is the best choice. For a desired speed of
1200 steps/second, set F switch to A. For a desired speed of 13000 steps/second, only an F switch
setting of 0 will suffice.
SETTING THE M SWITCH
Now that we have selected the F switch setting, we can find the value for M from Table 2. The factor
setting is in the left hand column, and the Max Speed setting is along the top row. In example 1 for the
desired M of 4500 steps/second, we set the F switch at 4. Table 1 lists the maximum speed values for
each switch setting of F. Looking at the M values in Table 2 for an F switch setting of 4, the closest
speeds are 4495 (M=C) and 4631 (M = D). For the desired maximum speed of 1200 steps/second
(F=9) and M switch setting of 0 (1207 sps) or A (1173 sps) can be used. A speed of 13000 sps (F=0)
requires an M switch setting of either A (12737 sps) or B (13102 sps).
SETTING THE B SWITCH
By choosing an F value, we restrict our choice of Base Speed to 16 possible values (see Table 3). In
example 1, from maximum speed of 4500 steps/second (F = 4) we can select Base speeds ranging
from 42 to 1223 steps/second. For the desired maximum speed of 1200 sps (F=9), the Base speed can
be chosen from a range of 15 sps to 438 sps. If due to the selection of the factor we are limited to a low
Base Speed, it is possible to choose a lower Factor and then choose the appropriate Base and Max
settings. Thus, for maximum speed of 1200 sps, a Factor of A could also be used, giving the range of
Base Speed 11 to 339 sps.

HOMING MODES
There are two Homing Modes that may be initiated, H0 and H1.
H0 HOMING MODE: This mode causes the motor to run at Max Speed in the direction selected. The
motor runs until the nut encounters the SOFT limit switch, at which time the motor decelerates to the
Base Speed. The nut continues to run at Base Speed until it hits the Home limit switch. This may
be illustrated by using a step motor driving a leadscrew as shown below. CAUTION: The two limit
switches should be placed such that the nut after hitting the Soft limit switch has enough time to get to
Base Speed before encountering the Home limit switch.
H1 HOMING MODE: When this homing mode is selected, the nut seeks home at Max speed. It decelerates to Base
speed when the soft limit switch is encountered. The Soft limit switch must remain closed until the motor completely
decelerates to Base speed, at which time the controller causes the motor to reverse direction and run at Base speed
until the Soft limit switch is no longer closed. This mode is illustrated below. This Homing mode uses only one
switch, but a flag is required to keep the switch closed during the deceleration cycle. If only a momentary switch
closure is made, the motor will decelerate to Base speed and stop. This stopping point may not be accurate or
repeatable; so, the flag is necessary.

SETTING THE MOVE DISTANCE
The index count or move distance for the DPF72452XCE can be accomplished by a number of meth-
ods. 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. 
						

							#L0101477 17        June 2008 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 ounted
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 avail-
able in 3, 4, 5, or 6 decades. The module is connected via a supplied 5-lead cable.
  Figure 8
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.

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.

0 = LOW ( 0 - 0.8Vdc), 1 = HIGH ( 3.5 - 5Vdc)
Select line #4 is only used if additional count input devices are “daisychained” to the expansion connec-
tor (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.
