PID Setpoint Input Methods
■
The PID setpoint input depends on the PID function setting in parameter b5-01.
If parameter b5-01 is set to 1 or 2, the frequency reference in b1-01 (or b1-15) or one of the inputs listed in
becomes the PID setpoint.
If b5-01 is set to 3 or 4, then the PID setpoint can be input from one of the sources listed in
PID Setpoint Sources
Analog input 1
Analog input 2
MEMOBUS/Modbus Register 0006H
Parameter b5-19
Note: A duplicate allocation of the PID setpoint input will result in an oPE alarm.
■ PID Feedback Input Methods
Either one feedback signal can be input for normal PID control, or two feedback signals can be input to control a
differential process value.
Normal PID Feedback
The PID feedback signal can be input from one of the sources listed below.
PID Feedback Source
Analog input 1
Analog input 2
Note: A duplicate allocation of the PID feedback input will result in an oPE alarm.
Differential Feedback
The second PID 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.
PID Differential Feedback Source
Analog input 1
Analog input 2
Note: A duplicate allocation of the PID differential feedback input will result in an oPE alarm.
