Displaying measurements
When a measurement has been performed or loaded from the database the graph form is displayed. Here one can
see how the speed, position and analogue values have changed during the measurement.
X- and Y-axes
Time is shown along the x-axis. If Smart has received a positive signal from the selected stop signal, that signal
marks the time zero (0). The time before that signal is regarded as negative time. If no stop signal has been
received the time zero is the start of the measurement. Speed, position and analogue values are shown along the
y-axis. Be sure to read from the correct y-axis when several graphs are shown at the same time in the graph
window.
Stop time data
If the stop time can be calculated a table containing
stop time data is shown in the top right corner of the
graph window.
The column "Stop signal" shows the speed and position
at the moment the stop signal was given.
The column "2 mm" shows the stop time and stop distance calculated from the stop signal to the position 2 mm
before the movement ceased. The column also contains the speed and position at 2 mm before stand still.
The centre column shows values for an adjustable stop speed. 10 mm/s is default but values between 0 and 99
mm/s can be selected. The column shows stop time, stop distance and position calculated from the stop signal to
the moment when the speed falls below the selected stop time. The overrun distance is the distance the machine
has moved in the same direction after the speed fell below the selected stop speed. If the overrun distance is
positive it is displayed in red digits in the table.
