structions
5.3.2 6-8* Analog Output 4 MCB 113
Parameters for configuring the scaling and limits for analog output 4. Terminal X45/3 and X45/4. Analog outputs are current outputs: 0/4 – 20 mA.
Resolution on analog output is 11 bit.
6-80 Terminal X45/3 Output
Option:
[0] * No operation
6-81 Terminal X45/3 Output Min Scale
Option:
[0.00%] * 0.00 - 200.00%
6-82 Terminal X45/3 Output Max Scale
Option:
[0.00%] * 0.00 - 200.00%
6-83 Terminal X45/3 Output Bus Control
Option:
[0.00%] * 0.00 - 100.00%
6-84 Terminal X45/3 Output Timeout Preset
Option:
[0.00%] * 0.00 - 100.00%

5.4 14-** 24 V DC External Supply

5.4.1 14-8* Options
14-80 Option Supplied by External 24VDC
Option:
[0] No
[1] * Yes
NB!
This parameter is only changing function by performing a power cycle.
Function:
Select the function of Terminal X45/3 as an analog current output.
Same selections available as for par. 6-70
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, i.e. 0 mA (or 0 Hz) is desired at 25% of the
maximum output value and 25% is programmed. The value can never be higher than the corre-
sponding setting in par. 6-82 Terminal X45/3 Max. Scale if value is below 100%.
This parameter is active when option module 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
desired 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 desired output current at a value between 0 - 100% of the ful-scale output, program the per-
centage value in the parameter, i.e. 50% = 20 mA. If a current between 4 and 20 mA is desired at
maximum output (100%), calculate the percentage value as follows (example where desired max.
output is 10 mA):
I RANGE mA
x 100 % =
I DESIRED MAX mA
Function:
Holds the level of output 4 (X45/3) if controlled by bus.
Function:
Holds the present level of output 4 (X45/3). In case of a bus timeout and a timeout function is
selected in par. 6-80 Terminal X45/3 Output the output will preset to this level.
Function:
Select No [0] to use the drive's 24 V DC supply.
Select Yes [1] if an external 24 V DC supply will be used to power the option. Inputs/Outputs will
be galvanically isolated from the drive when operated from an external supply.
