Automatic error acknowledgement

(Automatic fault acknowledgement)

S

0 ... 7

{ 0 }

In addition to the manual fault acknowledgement, an automatic acknowledgement can also be
selected.

0 = No automatic fault acknowledgement.

1 = ... 5 = Number of permissible automatic malfunction acknowledgments within one

mains-on cycle. After mains off and switch on again, the full amount is again available.

6 = Always, an fault message will always be acknowledged automatically if the cause of the

error is no longer present.

7 = via enable deactivation, acknowledgement is only possible using the ENTER key or by

mains switch-off. No acknowledgement is implemented by removing the enable!

NOTE: If (P428) is parameterised to "ON", parameter (P506) "Automatic fault
acknowledgement" must not be parameterised to setting 6 "Always" as otherwise the device or
system is endangered due to the possibility of continuous restarting in the case of an active
error (e.g. short-circuit to earth / short circuit).

P509

Control word source

(Control word source)

S

0 ... 4

{ 0 }

Selection of the interface via which the FI is controlled.

0 = Control terminals or keyboard, "Control terminal or keyboard control" ** with the

SimpleBox (if (P510)=0), the ParameterBox or via BUS I/O Bits.

1 = Only control terminals *, the FI can only be controlled via the digital and analog input

signals or via the bus I/O bits.

2 = USS *, the control signals (enable, rotation direction, etc.) are transferred via the RS485

interface, the setpoint via the analog input or the fixed frequencies.

3 = System bus*

4 = System bus broadcast *

*)

Keyboard control (SimpleBox, ParameterBox, PotentiometerBox) is disabled,
parameterisation is still possible.

**) If the communication during keyboard control is interrupted (time out 0.5 sec), the

FI will disable without an error message.

NOTE:

For details of the optional bus systems, please refer to the relevant supplementary bus
manuals (BU02x0).

Setpoint source

(Setpoint source)

S

0 ... 4

{ [-01] = 0 }

{ [-02] = 0 }

Selection of the setpoint source to be parameterised.

[-01] = Main setpoint source

[-02] = Subsidiary setpoint source

Selection of the interface via which the FI receives the setpoint.

0 = Auto: The setpoint source is

automatically derived from the
setting in the parameter P509
>Control word source<.

1 = Only control terminals, digital and

analog inputs control the frequency,
including fixed frequencies

2 = USS

3 = System bus

4 = System bus broadcast
