P509

Control word source

0 ... 4

{ 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*
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 Manual BU 0250.

As an alternative to setting the parameter, System Bus Broadcast can be selected with DIP
switch 3.

P510

... [-01]

... [-02]

Setpoint source

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 source of the auxiliary setpoint is

automatically derived from the setting in the
parameter P509 >Interface<

1 = Control terminals, digital and analog inputs

control the frequency, including fixed frequencies

2 = USS
3 = System bus
4 = System bus broadcast

P513 Telegram

downtime

-0.1 / 0.0 /
0.1 ... 100.0 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.

Note:

In BUS mode (e.g.: CANopen), monitoring is controlled via parameter (P120). Settings in
parameter (P513) therefore have no effect.

Exception: Setting {-0,1}
