Enter the set point across inverter terminals 2-5 or in Pr. 133 and enter the process
value signal across inverter terminals 4-5. At this time, set "20" or "21" in Pr. 128.
Item
Entry
Description
Set 0V as 0% and
5V as 100%.
When "0" or "10" is set in Pr. 73
(5V selected for terminal 2).
Across terminals 2-5
Set 0V as 0% and
10V as 100%.
When "1" or "11" is set in Pr. 73
(10V selected for terminal 2).
Set point
Pr. 133
Set the set point (%) in Pr. 133.
Process value
Across terminals 4-5 4mA DC is equivalent to 0% and 20mA DC to 100%.
