SECTION 8 - CR192 J-tSPM Programming Instructions
8.1 Programming procedure
The ,."SPM is a user programmable device with a
wide range of set-points that enable operation with a wide
variety of ring-type and brush less synchronous motors.
This section deals with programming the ,."SPM for a ring-
type motor. The set-points will be explained and a prac-
tical example will be given. The example may be followed
step by step by the operator as a guide to program his
,."SPM for his motor.
In order to program set-points the JISPM must be placed in
the PROGRAM MODE. This can only be done when the motor is
not running. Any attempt to place the JISPM in the PROGRAM
MODE while the motor is running will be ignored. To enter the
PROGRAM MODE the following keystrokes must be entered:
SHIFT - PROGRAM
The JISPM responds with:
ACCESS CODE?
The operator must now enter the proper access code to
enable the PROGRAM MODE. If no response is given or an
incorrect access code is entered the JISPM will display:
INCORRECT CODE
and then return to the ready state. The correct access code is
192 and it must be entered before a built-in time delay expires.
When the correct access code is properly entered the ,."SPM
The small up arrow indicates that the JISPM is in the
PROGRAM MODE and the arrow will remain in the display as
long as the JISPM is in the PROGRAM MODE. This serves as a
reminder that the motor will not start until the PROGRAM MODE
is exited.
The JISPM is now prompting for the parameter number that
the operator wishes to change. Following is a table of the set-
points that may be programmed by the operator. Each set-point
has a parameter number which the JISPM is asking for in the
display above. The operator may enter the number of the
particular set-point he wishes to change or, if desired, the
ENTER key may be pressed and the JISPM defaults to the first
set-point. Table 2 gives a detailed explanation of each set-point
and information about the Front-panel Keyboard. Finally, a
programming example is given.
Once the parameter number is entered, press ENTER.
Display now shows current value of that parameter. Now press
#.
The parameter value is shifted to the left and a cursor (*) is
indicating that the JISPM is waiting for new value. Enter new
parameter, then press ENTER. The new parameter will now be
displayed. Press SCAN to proceed to the next parameter to be
changed and again follow the above procedure.
Once all the desired parameters are changed, store the new
values by pressing:
SHIFT-STORE
if all parameters were correctly entered, display should flash:
STORED-VERIFIED
will display:
