Prog Mode Speed Set Program

To create a Prog Speed Set Program, proceed as follows:

1) Press the

PROG SPEED

key.

2) Choose an available speed set program from the list on the screen using the numeric keys to enter

the location number. The screen, as explained in the preceding section, will automatically
switch from Figure 9 to Figure 10.

3) Enter the first step speed using the numeric keys. The speed must be between 0.0 rpm and 250.0

rpm, in increments of 0.1 rpm.

4) Press the

key to accept the first step speed. The cursor moves to the time field.

5) Enter the first step time which may be any time other than 00:00 and must be between 1 second

and 99 minutes, 59 seconds. The format is MM:SS (Minutes Minutes:Seconds Seconds). The
default time is 00:05.

Press the

key to accept the time entry. The cursor moves back to the speed field.

Note: If you wish to change any entry in either the speed or time field, you need only enter (write

over) the entry and accept again by pressing the

key.

7) Press the

PROG RUN

key to accept the first step. The display changes to the second step.

8) Repeat steps 3 through 7 for as many steps (up to a maximum of 25 steps) as are required.

9) If the program is to have less than 25 steps, the End Program Entry command is given by entering

“0” for both step speed and time values as the final program step. If the program is to have 25
steps, the entry mode is ended automatically after the 25th step.

Prog Mode Speed Set Notes:

a) The

key has two functions:

1) Accepts the value just entered.
2) Moves the cursor between the speed field and the time field.

b) In any Prog Speed mode program, the step time that you accept in any step is presented as the

default time for the next step.
