6-51 Terminal 42 Output Min Scale
Default value: 0%
Conversion index: -2
Scale for the minimum output (0 mA or 4 mA) of the analog signal at terminal 42. Set the value to be the percentage of the full
range of the variable selected in parameter 6-50 Terminal 42 Output.
Parameter 6-52 Terminal 42 Output Max Scale
Table 426: Parameter 6-52 Terminal 42 Output Max Scale
6-52 Terminal 42 Output Max Scale
Default value: 100%
Conversion index: -2
Scale the maximum output of the selected analog signal at terminal 42. Set the value to the maximum value of the current signal
output. Scale the output to give a current lower 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 0–100% of the full-scale output, program the percentage value in the pa-
rameter, that is 50% = 20 mA. If a current 4–20 mA is required at maximum output (100%), calculate the percentage value as follows:
20 mA/desired maximum current x 100%
