If an analogue input is used with 4-20mA or 20-4mA current loop modes the respective bit (Pr 7.28 - analogue input 2 and Pr 7.29 -3) is set to one if
the current falls below 3mA. If the current is above 3mA with these modes or another mode is selected the respective bit is set to zero.

An offset can be added to each analogue input with a range from -100% to 100%. If the sum of the input and the offset exceeds ±100% the results is
limited to ±100%.

This offers a simple control of Pr 7.19 to change the source for the analogue output for use from Menu 0. When this parameter is set to 0 or 1 the
drive constantly writes Pr 5.01 or Pr 4.02 to Pr 7.19 respectively.

Update rate Background
The IGBT junction temperature is calculated using Stack 1 temperature (Pr 7.04) and a thermal model of the drive power stage. The resulting
temperature is displayed in this parameter. The calculated IGBT junction temperature is used to modify the drive switching frequency to reduce losses
if the devices become too hot (see Pr 5.18 on page 109).
