Omron FQM1-MMP21, FQM1-CM001 Analog Input Functions, Section, Sensor pressure, displacement, etc

Analog Input Functions Section 7-9

The PRV(881) instruction can also be used to read the latest analog input value through immediate refreshing. Analog signals can be input from pres- sure sensors, position meters, or sensors that require high-speed input pro- cessing such as a displacement sensors/end-measuring sensors. Consequently, this function allows simple, low-cost pressure control, tension control, or other control applications requiring high-speed mechanical mea- surement (distortion/thickness/length).

Sensor

(pressure, displacement, etc.)

Selected signal range: −10 to +10 V, 0 to 10 V, 0 to 5 V, 1 to 5 V, or

4 to 20 mA

Note The analog input responsiveness has been set relatively high to increase the processing speed. The high responsiveness may result in input signal distor- tion by external noise or interference. Take steps to suppress noise if the Motion Control Module is being used in an environment with a lot of noise. When the Motion Control Module’s analog input value is being used, addi- tional noise countermeasures can be added to the program such as using END refreshing and filtering the input values with AVG instructions.
