■ PI Setpoint Input Methods
The PI setpoint input depends on the PI function setting in parameter b5-01.
If parameter b5-01 is set to 1, the frequency reference in b1-01 (or b1-15) or one of the inputs listed in Table 5.8 becomes
the PI setpoint.
If b5-01 is set to 3, then the PI setpoint can be input from one of the sources listed in Table 5.8.
Table 5.8 PI Setpoint Sources
Note: A duplicate allocation of the PI setpoint input will result in an oPE alarm.
■ PI Feedback Input Methods
Either one feedback signal can be input for normal PI control, or two feedback signals can be input for controlling a
differential process value.
Normal PI Feedback
The PI feedback signal can be input from one of the sources listed below.
Table 5.9 PI Feedback Sources
Note: A duplicate allocation of the PI feedback input will result in 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.
Table 5.10 PI Differential Feedback Sources
Note: A duplicate allocation of the PI differential feedback input will result in an oPE alarm.
