Using  the  UPD  motor  driver  package,  the  system 

designer has total control over all of the important motion 

profile parameters. As shown in Figure 

2

,

each step pulse 

received by the driver results in a motor movement of one 

step.  This  makes  control  oL velocity,  acceleration,  de· 

:::eleration and position simply a matter of controlling the 

frequency  (pulses  per  iecond)  and  number  of  pulses 

sent to the driver. 

A velocity of exactly one revolution per second can be 

obtained from a 0.72 degree motor by sending pulses to 

the  driver  at  500  pulses per second. Acceleration and 

deceleration of the motor can be regulated by adjusting 

the frequency of  the pulses sent to the driver. 

Position  can  also  be  readily  controlled  because  the 

amount  or  motor  movement is  equal  to  the  number  of 

pulses applied to the driver, times the motor step  angle. 

For example, a 0.72 degree motor can be made to rotate 

exactly  one  revolution  by  applying  500  pulses  to  the 

driver. 

Figure 3shows a typical motion profile. In the time bet­

ween T1  and T2, the lrequency

·

of the pulses being sent to 

the  driver  increases,  causing  the  motor  to  accelerate. 

Between T2 and T3, the dnver receives pulses at a fixed 

rate, and the motor turns at constant velocity. The pulses 

to the driver decrease in frequency between T3 and T4, 

until they stop. This causes the motor to slow down and 

halt.  The  amount  of  shalt  rotation in degrees  is deter­

mined by multiplying the total number of pulses between 

T1  and  T4  by  the  number  of  degrees  per  step  of  the 

step motor 

The input pulse waveform is shown in Figure 4.A logical 

"ON" or"HIGH" is 4-5 volts, and "LOW" is be1ween 0-0.5 

volts. The input pulse should have TIL timing characteris­

tics: (i.e., the pulse rise and fafl times must be less than 1 

microsecond).  The  noise  liltering  in  the  U PO  driver 

requires that the input pulses be stable for a minimum of 

10 microseconds. 

In the "1  PULSE" mode, the motor will rotate one step for 

each pulse received at the driver's "PULSE" (STEP)  ter­

minal.  The  motor  moves  when  the  trailing  edge  of  the 

pulse is detected.  (See Figure 2.)  The direction of rota­

tion is controlled by the signal at the "CW/CCW" (DI REC­

TION)  terminal  of  the  driver  When  the  "CW/CCW" 

(DIRECTION)  terminal  is  "HIGH",  the  motor  will  rotate 

one  step  clockwise  for  each  pulse  received  at  the 

"PULSE" (STEP) terminal. The motor will rotate one step 

counter-clockwise for each pulse received at the "PULSE" 

terminal when the signal at the "CW/CCW" (DIRECTION)
