Can the Altivar 58 Analog Input 1 (AI1) be used for a 0-10 VDC process feedback signal when PI regulator control is being used?

No. AI1 can only function as a PI setpoint or a manual speed reference depending on the programming. AI1 can not function as a feedback signal. AI2 is the default PI feedback signal.

If a 0-10V feed back input signal is desired use the Analog I/O Option Card, VW3A58201U or Digital I/O extension card VW3A58202U. AI3 can be used as PI feedback.

Also, it is possible to use a signal converter to change 0 to 10v signal to 4-20 mA and use AI2 for the feedback.
This device standard part number is 31158-297-50 or as with ordering the Econoflex the J09 option.
