• These parameters (reference and analog min. and max. settings) provide scale and offset adjustment for the
reference.
• See figure at parameter 1104.
Example.
To set the minimum analog input value to 4 mA:
• Configure the analog input for 0…20 mA current signal.
• Calculate the minimum (4 mA) as a percent of full range (20 mA) = 4 mA / 20 mA * 100% = 20%
