Analog Voltage Output
Analog voltage signal for CH1 can be obtained through the MON terminals.
The LS controller has been factory-set to convert a range from -60 mm to
+60 mm into a voltage range from -6 V to +6V. (No voltage signal is provided
for CH2. If voltage signal for CH2 is required, consult the KEYENCE distribu-
tor.)
Analog voltage range: A range between -6 V and +6 V can be set to
match a desired measurement range. Any value between -999.9999 and
9999.9999 can be selected. Note, however, that the difference between the
maximum and minimum measurements (those that you specify to corre-
spond respectively to +6 V and -6 V) must fall within a range between 0.024
mm and 240 mm.
Calibration: When the segment selectors are calibrated, the analog voltage
signal through these terminals and RS-232C interface is automatically sent
based on the calibrated value.
Offset: When the segment selectors are calibrated, the selected offset
value is added to the analog voltage signal sent through these terminals and
RS-232C interface.
The analog voltage which appears on the main display and that which is
output through the MON terminals are always the same.
