Parameter Descriptions
3.7.10 6-81 Terminal X45/3 Min. Scale
6-81 Terminal X45/3 Min. Scale
Range: Function:
0 % [0 - Scales the minimum output of the selected analog
*
200 %] 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%.
This parameter is active when VLT
Relay Card MCB 113 is mounted in the frequency
converter.
3.7.11 6-82 Terminal X45/3 Max. Scale
6-82 Terminal X45/3 Max. Scale
Range: Function:
100 [0 - Scales the maximum output of the selected
% 200 % 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):
I mA
RANGE
x 100 %
I mA
DESIRED MAX
20 − 4 mA
= x 100 % = 160 %
10 mA
6-83 Terminal X45/3 Bus Control
Range: Function:
0 % [0 - 100 %] Holds the level of output 4 (X45/3) if
*
controlled by bus.

6-84 Terminal X45/3 Output Timeout Preset

Range: Function:
0 % [0 - Holds the preset level of output 4 (X45/3). If
*
100 %] 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.

NOTICE
This parameter cannot be adjusted
while the motor is running.
The options 12 and 13 are only
available for software version 48.XX.
Select the feedback source for the speed PID
controller.
The feedback may come from a different
encoder (typically mounted on the
application itself ) than the motor-mounted
encoder feedback selected in
parameter 1-02 Flux Motor Feedback Source.
Use the feedback source selected as motor
feedback in parameter 1-02 Flux Motor
Feedback Source.
