Set Point - The set point can be adjusted to any speed (or ratio) by pressing SET
POINT,
entering a new speed using the number keys, and pressing
ENTER.
This
changes the programming of the current set point (Set Point 1,2,3,4 or Ratio 1,2,3,4).
The motor will immediately ramp to the new setting. If you wish to change a
non-selected set point, press
SET POINT, then press the UP or DOWN arrows until the
desired set point is displayed, and enter the new set point.
Note: Decimal locations are fixed via programmable variables, and are not entered when
changing setpoints. The front panel LED displays will indicate which
set poi

Using the Arrow Keys to Alter Set Points -
Minor adjustments to the set point
can be made by pressing the
UP
or
DOWN
arrows while the system is running. If an
UP or DOWN
arrow key is pressed, the active set point will increase or decrease. The
rate of this change will increase if the key is held.
Programming THE VARIABLES:
The MicroSpeed 196 is programmed by entering data into a menu of variables. Only the
variables that affect operation of the unit as it relates to the application must be
programmed. Upon power up, the MicroSpeed 196 will display
READY
on the alpha-
numeric display. This indicates that the MicroSpeed 196 is ready for operation or program-
ming. To program a variable, press
VAR
on the front panel keypad. The alphanumeric
display will prompt for a variable number, and the numeric display will indicate two
zeros (00), which will reflect the variable number entered. Enter the desired variable
number and press
ENTER .
If you are unsure of the variable, the
UP and DOWN
arrows on the keypad will allow you to scroll through the menu of variables. As you
9
scroll, the numeric display will indicate the number of the variable, and the alpha-
numeric display will name the variable. Press
ENTER
when the desired variable is
displayed.
When the variable to be programmed is accessed, enter data using the numeric keys, and
then press
ENTER.
Note: A decimalpointcannot lead an entry; the decimal placemust be preceded by a zero (0).
After
ENTER
is pressed, the display will ask for another variable number. If there is no
other variable data to be entered, press the
VAR
key to return to the
READY
mode.
