 Pr.10.18 set value is the conversion base of the corresponding relationship between the sensor
feedback analog quantity and the feedback physical quantity, and usually set to the maximum
value of the sensor input range physical quantity.
 Select Pr.10.01 value according to the sensor output signal type 0–10 V/ 4–20 mA and specific
control requirements.
 The sensor output range is 4–20 mA, the feedback physical quantity = (sensor measurement
feedback current - 4) ÷ (20 - 4) × Pr.10.18.
 The sensor output range is 0–10 mA, the feedback physical quantity = (sensor measurement
feedback voltage - 0) ÷ (10 - 0) × Pr.10.18.
 For example, the pressure sensor range is 0–16.0 bar, and the corresponding output range
is 4–20 mA. When the Pr.10.18 is set to 16.0 and the sensor's actual measurement output is
12 mA, the actual feedback physical quantity = (12 - 4) ÷ (20 - 4) × 16.0 = 8.0 bar, the
corresponding relationship is shown in the table below.
 Set Pr.00.03 = 3 and Pr.00.04 = 8 to display the actual feedback physical quantity on the digital
keypad. And the physical quantity correspond to the feedback value displayed on the right side
of ":". Refer to Pr.00.04 description for more details.
