6-52 Terminal 42 Output Max Scale
Range: Function:
100.00 %* [0.00 - 200.00 %] Scale for the maximum output (20 mA) of the analog signal at terminal 42.
Set the value to be the percentage of the full range of the variable selected in par. 6-50 Terminal
42 Output .
130BA075.11
It is possible to get a value lower than 20 mA at full scale by programming values >100% by using
a formula as follows:
20 mA / desired maximum current × 100 %
i . e . 10 mA :
20 mA
10 mA
× 100 % = 200 %
EXAMPLE 1:
Variable value= OUTPUT FREQUENCY, range = 0-100 Hz
Range needed for output = 0-50 Hz
Output signal 0 or 4 mA is needed at 0 Hz (0% of range) - set par. 6-51 Terminal 42 Output Min Scale to 0%
Output signal 20 mA is needed at 50 Hz (50% of range) - set par. 6-52 Terminal 42 Output Max Scale to 50%
130BA858.10
EXAMPLE 2:
Variable= FEEDBACK, range= -200% to +200%
Range needed for output= 0-100%
Output signal 0 or 4 mA is needed at 0% (50% of range) - set par. 6-51 Terminal 42 Output Min Scale to 50%
Output signal 20 mA is needed at 100% (75% of range) - set par. 6-52 Terminal 42 Output Max Scale to 75%
