Maximum Reference
Function:
Scale for the minimum output (0 or 4 mA) of the analogue signal at terminal 42.
Set the value to be the percentage of the full range of the variable selected in par. 6-50

Function:
Scale for the maximum output (20 mA) of the analog signal at terminal 42.
Set the value to be the percentage of the full range of the variable selected in par. 6-50
