text: <s>[INST] PF400 Analog Output not linear with Output Freq. Hi all,I have this problem regarding the linearity of my Analog Output in correspond to the Output Frequency.. this is a Power flex 400, Setting as Follows:Min Freq: 20Hz (parameter 34)Max Freq: 45Hz (Parameter 35)Parameter 82 set to 0 ( VFD analog output req. 0-10V)- Everything is running fine I can command the speed via a third party PLC via 0-10V Analog signal, the commanded voltage is in linearity with the Output Frequency, But the output frequency cannot.. anything I miss out. please help. Gnix [/INST] Looking at the User Manual, if parameter T082 is configured to 0 - OutFreq 0-10, the corresponding minimum output value is 0 volt at 0 Hz. Try to configure it to 21 - MinFreq 0-10 so that your Min Freq corresponds to 0 volts at Analog Out. Hope this helps… - fuzzy logic \\n </s>
