Max. freq. a-in 1/2
(Maximum frequency a-in 1/2 (auxiliary setpoint
value))
P
-400.0 ... 400.0 Hz
{ 50.0 }
The maximum frequency that can act on the setpoint via the auxiliary setpoints.
Auxiliary setpoints are all frequencies that are additionally delivered for further functions in the FI:
Actual frequency PID Frequency addition Frequency subtraction
Auxiliary setpoints via BUS Process controller
Min. frequency above analog setpoint (potentiometer)

Fixed specification of a setpoint for the process controller that will only occasionally be altered.
Only with P400 = 14 ... 16 (process controller). Further details can be found in Chap. 8.2

PID control P comp.
(P-component of PID controller)
S P
0.0 ... 400.0 %
{ 10.0 }
This parameter is only effective when the function PID actual frequency is selected.
The P-component of the PID controller determines the frequency jump if there is a control
deviation based on the control difference.
E.g.: At a setting of P413 = 10% and a rule difference of 50%, 5% is added to the actual setpoint.

PID control I comp.
(I-component of PID controller)
S P
0.0 ... 3,000.0 %/s
{ 10.0 }
This parameter is only effective when the function PID actual frequency is selected.
The I-component of the PID controller determines the frequency change, dependent on time.
Up to SW 1.5 the setting range was 0.00 to 300.00 ‰/ms! This can cause incompatibilities in the
transfer of data sets between FIs with different software versions.

PID control D comp.
(D-component of PID controller)
S P
0 ... 400.0 %ms
{ 1.0 }
This parameter is only effective when the function PID actual frequency is selected.
If there is a rule deviation, the D-component of the PID controller determines the frequency
change multiplied by time (%ms).
If one of the analog inputs is set in the function actual value process controller, this parameter
determines the controller limitation (%) after the PI controller. For further details, see Section 8.2.
