P412

Nom.

val.

process ctrl.

(Nominal value 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 technical details can be found in
Section 9.2.

P413

PI control P comp.

(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.

For example: At a setting of P413 = 10% and a control difference of 50%, 5% is added to the
actual setpoint.

P414

PI control I comp.

(I-component of PI controller)

S

P

0.0 ... 3000.0 %/s

{ 10.0 }

This parameter is only effective when the function PI controller actual frequency is selected.

In case of a control deviation, 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 control control limit

(Process controller control limit)

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

Ramptime PI setpoint

(Ramp time PI setpoint value)

S

P

0.00 ... 99.99 s

{ 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).

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)
