AN-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. AN-50 Terminal 42
Output
.

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. 10mA : 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. AN-51 Terminal 42 Output Min Scale to 0%
Output signal 20 mA is needed at 50 Hz (50% of range) - set par. AN-52 Terminal 42 Output Max Scale to 50%
