Selection of the interface via which the FI is controlled.
0 =
Control terminals or keyb. cont., "Control terminals or keyboard control" ** with the
SimpleBox (if P510=0), the ParameterBox or via BUS I/O bits.

Only control terminals *, the FI can only be controlled via the digital and analogue inputs
or via the bus I/O Bits.

USS *
, the control signals (enable, rotation direction, etc.) are transferred via the RS485
interface, and the setpoint is transferred via the analogue input or the fixed frequencies.
3 =
System bus *, setting for actuation by master via a bus interface
4 =
System bus broadcast *, setting for actuation by a master drive in Master / Slave mode
(e.g. with synchronous applications)
*) Keyboard
control (SimpleBox, ParameterBox) is disabled, parameterisation is still
possible.
**) If communication is interrupted during keyboard control (timeout 0.5 sec), the FI will
block without an error message.
NOTE:
For details of the optional bus systems, please refer to the relevant supplementary bus manuals.
