Acceleration/Deceleration Curves; Actual Vs Desired Speed - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

Microflite Ultra 2000
When the 0 button is pressed while on 'View previous events', the event previous to the one presently
shown is displayed, until the least current fault is on the screen. Pressing 0 while on 'View next event'
brings the next event to the screen, until the most current event is displayed. Pressing 0 while on 'View
latest event' causes the display to move to the most recent event. When 0 is pressed while on 'Clear
fault memory', all stored events are cleared. The ? Faults Detected? message on the main diagnostic
screen will still display that faults have been detected after the fault memory is cleared until the main
processor has been reset.

11.5.3 Acceleration/Deceleration Curves

To access this screen, the cursor must be moved until it is blinking in the top right hand corner of the
Fault / Hall Call Screen. Then the 0 key is pushed. Screen 3 is used to display the acceleration and
deceleration curves. The cursor is used to select the mode of operation. When the cursor is moved to
the mode area on the bottom right of the screen, pressing the 0 button will either turn off the curve
display or bring up either the acceleration or deceleration curve display. Two graphs are displayed.
The top graph displays the desired speed versus time and the bottom graph displays the actual speed
versus time. The screen will only be updated when the motion status on the bottom left corner of the
screen says "Halt".
ACC / DEC Screen Displays
To access this screen, the cursor must be moved until it is blinking in the top right hand corner of the
Accel / Decel Curve Screen. Then the 0 key is pushed
To change modes of the display, move the cursor to bottom left corner of the screen and press the 0
key until the desired mode is selected. The display mode can only be changed while the car is halted.
The status of the car will be displayed at the bottom left hand side of the screen as either "HALT" or
"RUN". Located on the lower right hand corner of the screen, is an indicator of whether the display is
set to acceleration, deceleration or off. The following are the three display modes.
OFF - In this mode no curve updates occur.
Acceleration Display - In this mode the speed curve generated in the first 5 seconds of motion, after
the car leaves a floor, is displayed.
Deceleration Display - In this mode the speed curve generated in the last five seconds of motion,
before the car is halted at the floor, is displayed.
11.5.4 Actual vs. Desired Speed
Screen 4 is used to display the difference between the actual speed and the desired speed (i.e. -
speed error). The cursor can be moved to two sections of the screen, ACC/DEC or GAIN. If the 0
button is pressed when the cursor is on gain selection, it will change the scale of the display to look
more closely at the actual difference between desired and actual. There are four different gains: x1; x2;
x4 and x8. The gain may be changed, only when the car is halted.
The lower left and right hand corners display the same mode and motion information as on screen 3.
The mode of operation may be altered when the cursor is positioned on mode of operation selection,
using the 0 button. In the ACC mode, the first 5 seconds of the previous run is displayed. In the DEC
mode, the last 5 seconds of the previous run is displayed.
