Multi-Function Contact Inputs (H1-01 to H1-05)
Multi-Function Analog Input (H3-09)
PI Control Methods
The PI control method can be enabled or disabled by setting parameter b5-01.
PI Feedback Input Methods
The multifunction analog input A2 can be used for PI control feedback input.
Therefore the parameter H3-09 (Multi-Function Analog Input Terminal A2 Selection) has to be set to B (PI-
feedback).
The PI feedback value can be adjusted by using the analog input terminal gain and bias.
PI Adjustment Examples
Suppressing Overshoot
If overshoot occurs, reduce Proportional gain (P) and increase integral time (I).
