6-52 Terminal 42 Output Max Scale
Range:
100.00 %* [0.00 - 200.00 %]
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
Output signal 20 mA is needed at 50 Hz (50% of range) - set par.6-52
Function:
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
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
20 mA
i . e . 10 mA : × 100 % = 200 %
10 mA
