PI error is the AO1,AO2,AO3percentage difference between desired setpoint and actual feedbackcompared to the feedback range. The analog output is scaled such that0 (or 4 mA) is proportional to -5%, and 20 mA is proportional to 5%.PI INTEGRATOR Analog output reference proportional to PI integral error.AO1,AO2,AO3FB LIMIT Logic output indicating that PI FLT RATIO has been exceeded.
