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
