TRANSIENT VOLTAGE 
 SUPPRESSION 
Transient Voltage Suppression (TVS) 
Diodes on the motor phase outputs 
allow for much longer motor cables to 
be used.  Normally when using long 
motor cables, voltage transients and 
spikes are created.  These transients 
often exceed the voltage ratings of 
the output phase transistors, resulting 
in blown transistors.  The addition of 
the TVS Diodes suppresses these 
transients and protects the transistors 
against damage.

INDEXER 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...

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  BUSY  This 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 place to provide TTL 
levels (see section on Jumpers). 
 
17  CLOCK  This output is an open collector output, 15 microseconds wide (minimum) that is the clock input for...

 USING THE MANUAL PRESET INDEXER 
 
 
SELECTING MOTION PARAMETERS 
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 6.   
They range from 2 steps/second to 
3,611 steps/second. 
 
MAX...

SETTING THE M SWITCH 
Now that we have selected the F switch setting, we can find the value for M from Table 5.    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 4 lists the maximum speed values for each switch setting of F.    Looking at the M values in 
Table 5 for an F switch setting of 4, the closest speeds are 4495 (M=C) and 4631 (M = D). For the...

SETTING THE B SWITCH 
By choosing an F value, we restrict our choice of Base Speed to 16 possible values (see Table 6).    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=A), the Base speed can be chosen from a range of 11 sps to 339 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...

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...
