Figure 3-9 Setting of Analog Output
Calibration method of Analog output
The zero point value and full range value of analog quantity are proportional to the
corresponding DA code (see table 4-3, explanation forSET 1 parameter 11 and 12). Calculation
and calibration of parameter 11 and 12 can be done by using the tolerance of Analog output.
Attention: in voltage output mode, short circuit of Analog output terminal is strictly
prohibited, so does the connection of load of 4-20mA current output. Or else, damage will
be caused to the Analog output circuit.
X. Detection of input and output hardware
When the main display is in the display internal code mode (select 1 for parameter A of
in SET 0), the detection can be done to check the condition of input and output
terminals. When I0 input terminal signal is effective, the corresponding O0 will have
control signal output. For the same reason, the I1 corresponds to O1……I7
corresponds to O7.
Attention: when external equipment is connected, try to avoid using this method to
detect input and output circuit so as to prevent any accident.
Under the displaying status of internal code, the indicating lamp for net weight reflects the
working status of ARM single-chip computer oscillator in main panel. When the indicating lamp
is on, it means that the external quartz resonator is operating normally while the off status of
indicating lamp means that the internal RC oscillator within single-chip computer is working.
