Is there any info on the how/what/where/etc on setting up a GS2 to perform PID control? I am going to be using one for level control using a 4-20MA level transmitter as feedback. The control willl be a cetrifigal pump pumping out of a reservoir. I cannot seem to find much info or how to videos on this.

Depending upon the drive and PID application, I use these parameters to get going.
Adjusting the Accel, Decel, Gain, Integral, and Derivative as necessary
P1.01 (5) Accel
P1.02 (5) Decel
*** This is where the 4-20 ma transmitter should go.
P4.00 Source of Frequency Command
Set Drive DIP Switch to 10-0Vdc or 4-20ma
(02) 0-10Vdc AVI
(03) 4-20ma AVI
P4.05 Loss of ACI signal 4-20 ma
(00) Decelerate to 0Hz
(01) Stop Immediately and display EF
(02) Continue Operation by the last frequency Command
P4.11 Analog Output Signal Current A Signal
(1) Output 0-10 Vdc
(2) Output 4-20 ma
P4.12 (100) Analog Output Signal Gain
P7.00 PID Setting
Set Drive DIP Switch to 10-0Vdc or 4-20ma
(00) Inhibit PID Operation
(01) FWD Acting PID Feedback from AVI 0-10Vdc
(02) FWD Acting PID Feedback from AVI 4-20 ma
(03) REV Acting PID Feedback from AVI 0-10Vdc
(04) REV Acting PID Feedback from AVI 4-20 ma
P7.01 (100.0) PV 100% Value
P7.02 (00) Pid Setpoint Keypad
P7.10 (XX.X) Pid Setpoint 0-999
Change PID Settings – Gain, Integral, and Derivative as necessary
P7.20 (1.00) PID Proportional 0.00 -10.0
P7.21 (1.00) PID Integral 0.00 – 100.0 (00.00 = Disabled)
P7.22 (1.00) PID Derivative 0.00 – 1.00
P7.25 (110) PID Freq Limit 0-110%
