P412
Setpoint process controller
(Setpoint value for process controller)
S P
-10.0 ... 10.0 V
{ 5.0 }
Fixed specification of a setpoint for the process controller that will only occasionally be altered.
Only with P400 = 6 or 7 (PID process controller). Further details can be found in Section 9.2 .
P413
P-component PI-controller
(P-component of PI-controller)
S P
0.0 ... 400.0 %
{ 10.0 }
This parameter is only effective when the function PI controller actual frequency is selected.
The P-component of the PI 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.
P414
I-component PI-controller
(I-component of PI-controller)
S P
0.0 ... 3,000.0 %/s
{ 10.0 }
This parameter is only effective when the function PI controller actual frequency is selected.
The I-component of the PI controller determines the frequency change, dependent on time.
Note: In contrast to other NORD series, parameter P414 is smaller by a factor of 100
(Reason: better setting ability with small I-components).
P415
Process controller limit
(Control limit of process controller)
S P
0 ... 400.0 %
{ 10.0 }
This parameter is only effective when the function PI process controller is selected. This
determines the control limit (%) after the PI controller.
For further details, see Section 9.2.
P416
Ramp time PI setpoint.
(Ramp time PI setpoint value)
S P
0.00 ... 99.99 sec
{ 2.00 }
This parameter is only effective when the function PI process controller is selected.

Offset analog output
(Offset analog output)
S P
-10.0 ... 10.0 V
{ all 0.0 }
[-01] = First IOE, AOUT of the first I/O extension (SK xU4-IOE)
[-02] = Second IOE, AOUT of the second I/O extension (SK xU4-IOE)
... only with
SK CU4-IOE or
SK TU4-IOE
In the analog output function an offset can be entered to simplify the processing of the analog
signal in other equipment.
If the analog output has been programmed with a digital function, then the difference between the
switch-on point and the switch-off point can be set in this parameter (hysteresis).
