Analog inputs The controller has an analog input with 10-bit resolution. It is located on pin 8 of X4. You can configure the analog input as a current input or as a voltage input with object 3221h. You can read out the analog value in a NanoJ program and use it as you like, e. g., to specify the target speed. Object entries To read out and, if necessary, manipulate the value of the analog input, use the following OD settings: 3220h (Analog Inputs): This object displays the instantaneous values of the analog inputs in ADC digits. 3221h: (Analogue Inputs Control): With this object, you can switch the analog input from voltage measurement to current measurement. 3320h (Read Analogue Input):This object displays the instantaneous values of the analog inputs in user-defined units. 3321h (Analogue Input Offset):This is the offset that is added to the read analog value (3220h) before scaling (multiplier from object 3322h and divisor from object 3323h). 3322h(Analogue Input Factor Numerator): This is the value by which the read analog value (3220h + 3321) is multiplied before it is written in object 3320h. 3323h(Analogue Input Factor Denominator):This is the value by which the read analog value (3220h + 3321h) is divided before it is written in object 3320h. Scale analog value You read the value in object 3320h (Read Analogue Input): This object displays the instantaneous values of the analog inputs in user-defined units. The user-defined units are made up of offset (3321h) and scaling value (3322h/ 3323h). If both are still set to the default values, the value in 3320h is specified in the ADC Digits unit. Example Analog input 1 has a measuring range of 0 V…+10 V. There is a voltage of 0 V…+10 V on the analog input, which, at a resolution of 10 bits, corresponds to the value range 0…1023 ADC digits. To display the analog value in the physical unit of millivolt, proceed as follows: Write the value "10000" (corresponds to the entire measurement range in millivolt) in 3322h:01h (Analogue Input Factor Numerator). Write the value "1023" (corresponds to the resolution in digits) in 3323h:01h (Analogue Input Factor Denominator). At the maximum voltage of 10 V, now read out the value "10000" in object 3320h (Read Analogue Input): 1023 digits * 10000 mV / 1023 = 10000 mV
