In modes 2 and 3, a current loop loss trip (cL) will be generated if the current input falls below 3mA.
If 4-20 or 20-4 modes are selected and the drive trips on current loop loss (cL), analog reference 2 cannot be selected if the current reference is less
then 3mA.
If 4-.20 or 20-.4 modes are selected, Pr 15.03 will switch from a 0 to 1 to indicate that the current reference is less then 3mA.
Terminal T3 is a voltage/current output. The setting of this parameter configures the terminal for the required mode.
This parameter displays the level of the analog signal present at analog input 1.
In voltage mode, this is a bipolar voltage input where the input range is -10V to +10V.
In current mode, this is a unipolar current input having a maximum measurable input of 20mA. The drive can be programmed to convert the measured
current to any one of the defined ranges in Pr 15.38. The selected range is converted to 0 - 100.0%.
This parameter is used to scale the analog input if so desired. However in most cases it is not necessary as each input is automatically scaled such
that for 100.0%, the destination parameters (defined by the settings of Pr 15.43) will be at maximum.
