6-51 Terminal 42 Output Min Scale

Range: Function:

0.00 %* [0.00 -

200.00 %]

Scale for the minimum output (0 or

4mA) of the analog signal at terminal 42.

Set the value to be the percentage of

the full range of the variable selected in

6-50 Terminal 42 Output.

6-52 Terminal 42 Output Max Scale

Range: Function:

100.00

[0.00 -

200.00

Scale for the maximum output (20mA) of the

analog signal at terminal 42.

Set the value to be the percentage of the full

range of the variable selected in 6-50 Terminal

42 Output.

It is possible to get a value lower than 20mA

at full scale by programming values >100% by

using a formula as follows:

EXAMPLE 1:

Variable value= OUTPUT FREQUENCY, range = 0-100 Hz

Range needed for output = 0-50Hz

Output signal 0 or 4mA is needed at 0Hz (0% of range) -
