In modes 2 and 3, a current loop loss trip (cL1) will be generated if the current input falls below 3mA.
NOTE
If 4-20 or 20-4 modes are selected and the drive trips on current loop loss (cL1), analog reference 2 cannot be selected if the current reference is less
than 3mA.
If 4-.20 or 20-.4 modes are selected, Pr 7.28 will switch from OFF to On to indicate that the current reference is less than 3mA.
NOTE
If both analog inputs (A1 and A2) are to be set-up as voltage inputs, and if the potentiometers are supplied from the drive's +10V rail (terminal T3),
they must have a resistance >4kΩ.
7.07 Unused parameter
7.08

Analog input 1 scaling

Bit SP
Coding
Range 0.000 to 4.000
Default 1.000
Update rate Background
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 7.10 and Pr 7.14) will be at maximum.
7.09

Analog input 1 invert

Bit SP
Coding
1
Range OFF(0) or On(1)
Default OFF(0)
Update rate 5 ms
This parameter can be used to invert the analog input reference (i.e. multiply the input scaling result by -1).
7.10

Analog input 1 destination

Bit SP
Coding
Range Pr 0.00 to Pr 21.51
Default Pr 1.36
Update rate Read on drive reset
As default, this parameter is set-up automatically according to the drive configuration (see Pr 11.27 on page 140).
Only parameters which are not protected can be controlled by analog inputs. If a non valid parameter is programmed to the destination of an analog
input, the input is not routed anywhere.
After a modification to this parameter, the destination is only changed when a reset is performed.
