Analog inputs The controller has an analog input with 10-bit resolution. It is located on pin 8 of X3. 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. The controller also offers pre-programmed operating modes (analog speed / joystick) that evaluate the analog input (see Special drive modes (clock-direction and analog 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
