Analog Input Adjustments
Analog Input Speed Reference and Output Frequency
Do not set the same frequency values for both output frequency levels 1 and 2. This will cause an Err1
detected fault.
When using a 4–20 mA signal, set speed reference level 1 value to 20% (4 ÷ 20 = 20%).
A further refinement of the bias and slope of the analog input signals can be made with parameters F470 –
F473.
