To start PID control, switch on the X14 signal. When this signal is off, ordinary inverter operation is
performed without the PID action being performed.
Enter the set point across inverter terminals 2-5 or into Pr. 133 and enter the process value signal across
inverter terminals 4-5.
When entering the externally calculated deviation signal, enter it across terminals 1-5. At this time, set "10" or
"11" in Pr. 128.

Set 0V as 0% and 5V as 100%.
Set 0V as 0% and 10V as 100%.
Set the set point (%) in Pr. 133.
Set − 5V as − 100%, 0V as 0% and + 5V as
