1.2 b: Application
If parameter b5-01 is set to 1 or 2, the frequency reference in b1-01 or one of the inputs listed in
setpoint.
If b5-01 is set to 3 or 4, then the PI setpoint can be input from one of the sources listed in
PI Setpoint Source
Analog Input A1
Analog Input A2
MEMOBUS/Modbus Register 0006 H
Parameter b5-19
Note: A duplicate allocation of the PI setpoint input will cause an oPE alarm.
n PI Feedback Input Methods
Input one feedback signal for normal PI control or input two feedback signals for controlling a differential process value.
Normal PI Feedback
Input the PI feedback signal from one of the sources listed below:
PI Feedback Source
Analog Input A1
Analog Input A2
Note: A duplicate allocation of the PI feedback input will cause an oPE alarm.
Differential Feedback
The second PI feedback signal for differential feedback can come from the sources listed below. The differential feedback
function is automatically enabled when a differential feedback input is assigned.
PI Differential Feedback Source
Analog Input A1
Analog Input A2
Note: A duplicate allocation of the PI differential feedback input will cause an oPE alarm.
