How can Reverse acting PI be set up in the ATV21 drive?

It can be done by reversing the scaling of the analog input (of the PID feedback).
The scaling is set with the parameters: F201 up to F204 for VIA and F210 up to F213 for VIB.

For example, you have a 4-20mA sensor feedback on VIA and if
you want reverse the scaling then set the parameter as follow :
F201=20% ; F202 = 60HZ and F203 = 100% and F204 = 0HZ.
