0 ... 21
{ 0 }
Selection of the interface via which the FI is controlled.
0 = Control terminals or keyboard control ** with the ControlBox (if P510=0), the
ParameterBox (not ext. P-box) or via BUS I/O Bits.
1 = Only control terminals , the FI can only be controlled via the digital and analog
inputs or via the bus I/O Bits.
8 = Profibus setpoint, the frequency setpoint is transferred via Profibus. Control via the
digital inputs is still active.
9 = Profibus control word, the control signals (enable, direction of rotation, ...) are
transferred via Profibus, the setpoint via the analog input or the fixed frequencies.
10 = Profibus, all control data is transferred via Profibus. The analog input and the digital
inputs have no function (except safety functions)
*) Keyboard control (ControlBox, ParameterBox, PotentiometerBox) is blocked,
parameterisation is still possible.
**) If the communication during keyboard control is interrupted (time out 0.5 sec),
the FI will block without an error message.

0.1 ... 1000 s
{ 0.0 }
Monitoring function of the active bus interface. Following receipt of a valid telegram, the next one
must arrive within the set period. Otherwise the FI reports an error and switches off with the error
message E010 >Bus Time Out<.
0.0 = Off: Monitoring is switched off.
-0.1 = No error: Even if communication between BusBox and FI is interrupted (e.g. 24V error,
Box removed, etc.), the FI will continue to operate unchanged.
