At this point, the user may Enter/Edit, Clear or Use a stored program (Speed Set). Let’s startwith
Enter/Edit by pressing the “1” key:
Figure 22
In this example, the user is informed that he has 6 speed sets (0,1,2,5,8,9) pre-programmed in
memory and 4 speed sets (3,4,6,7) not programmed and available. Select any one of the ten speed
sets by pressing the appropriate numeric key. Pressing the MOTOR ON/OFF/ESCAPE key at this
point would exit the user to the default PROGRAM MODES display (Figure 20). For now let’s
assume that the user wants to program a new speed set by pressing the “3” key (the first available
program slot).
ENTERING A SPEED SET (PROGRAM)
There are two (2) types of programs available to the user: programs with finite step time intervals
and programs with zero (0) step time intervals. We will cover the inputting of finite step time
programs first.
SPEED SETS WITH FINITE STEP TIMES (PROG SPEED)
These programs when executed will automatically progress from step to step based on the time
intervals programmed by the user. On pressing the “3” key in Figure 22 the user is presented with:
Figure 23
This screen reminds the user of the speed set that he has selected to program and then allows him
to change either the speed or time interval or both for that step.
Note: The time interval on entry to this screen will always be set to 00:05 seconds as the
default value. The user may of course change it to any valid time of his choice.
Whenever you change time interval, that new time becomes the default interval until
it is again changed by the user. Also, note that zero (0) times are not allowed for
program steps after the first step for Finite Step programs.
