{ 0 }
Selection of the interface via which the FI is controlled.
0 = Control terminals 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 *, the control signals (enable, direction of rotation, ...) are transferred via the
system bus (the field bus module and the frequency inverter communicate via the
system bus). I.e. the setting "3" - "System bus" must be selected in parameter (P509)
for control of the frequency inverter via the field 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).
As an alternative to setting the parameter, System Bus can also be selected with DIP switch 3.

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 = Control terminals, digital and analog inputs
control the frequency, including fixed frequencies
2 = USS
3 = System bus
4 = System bus broadcast
