Function:
(terminal X45/1) if controlled by bus.
Function:
Holds the preset level of analog output 3
(terminal X45/1).
If there is a fieldbus timeout and a
timeout function is selected in
parameter 6-70 Terminal X45/1 Output, the
output is preset to this level.

parameter 6-70 Terminal X45/1 Output.
Function:
Scales the minimum output of the selected
analog signal on terminal X45/3. Scale the
minimum value as a percentage of the
maximum signal value, for example, 0 mA
(or 0 Hz) is required at 25% of the
maximum output value and 25% is
programmed. The value can never exceed
the corresponding setting in
parameter 6-82 Terminal X45/3 Max. Scale if
the value is below 100%.

Function:
This parameter is active when VLT
Extended Relay Card MCB 113 is mounted
in the frequency converter.
Function:
Scales the maximum output of the
selected analog signal on terminal X45/3.
Scale the value to the required maximum
value of the current signal output. Scale
the output to give a lower current than 20
mA at full scale or 20 mA at an output
below 100% of the maximum signal value.
If 20 mA is the required output current at
a value between 0–100% of the full-scale
output, program the percentage value in
the parameter, for example, 50% = 20 mA.
If a current of 4–20 mA is required at
maximum output (100%), calculate the
percentage value as follows (example
where required maximum output is 10
mA):

Function:

Function:
Holds the preset level of output 4
(X45/3). If there is a fieldbus timeout and
a timeout function is selected in
parameter 6-80 Terminal X45/3 Output, the
output is preset to this level.
