The frequency inverter can be controlled completely via the serial interface. The following parameters
and actual values are used for this:
Parameter Setting
No. Name/Meaning Min. Max. Factory Setting Type
410 Control Word 0x0000 0xFFFF - uInt
411 Status Word 0x0000 0xFFFF - uInt
484 Ref. Frequency Value RAM [Hz] -999,99 999,99 0,00 Long
524 Ref. Percentage RAM [%] -300,00 300,00 0,00 Long
With the
Control Word
410 (data type uInt), control commands are sent to the frequency inverter.
With the
Reference Frequency RAM
484 (data type Long [Hz]) or
Reference Percentage RAM
524
(data type Long [%]), the reference line value is sent. Via the
Status Word
411 (data type uInt), the
status of the frequency inverter is read out.

Note:

484 and

524 are stored
in the RAM of the frequency inverter. This is generally addressed via data set 0.

412 Local/Remote
The frequency inverter can be controlled with various operation modes. These operation modes can
be selected with parameter
Local/Remote
412.
Local/Remote
412
Function
0 - Control via Contacts
The Start and Stop commands as well as the direction of rotation are
set via digital signals.
1 - Control via
Statemachine
The Start and Stop commands as well as the direction of rotation are
controlled via the Remote Statemachine
1
of the communication inter-
face.
2 - Control via Remote
Contacts
The Start and Stop commands as well as the direction of rotation are
controlled via virtual digital signals through the communication proto-
col.
For operation via the serial interface, settings 0, 1 and 2 are relevant. Further possible operation
modes
Local/Remote
412 are described in the frequency inverter operating instructions. These relate
to the control via the Operator Panel and the control via digital signals.
Parameter
Local/Remote
412 is data set related, i.e. by selecting a data set, you can switch over
between the different operation modes.

414 Data Set Selection
The data set switch-over can be carried out via control contacts at the digital inputs of the frequency
inverter or via the bus. For data set change-over via the bus, parameter
Data Set Selection
414 is
used.
Parameter Setting
No. Name Min. Max. Factory Setting
414 Data Set Selection 0 5 0
With the default setting
Data Set Selection
414 = 0, the data set change-over is carried out via the
digital inputs.
If
Data Set Selection
414 is set to 1, 2, 3 or 4, the selected data set is activated via the bus. At the
same time, data set change-over via the digital inputs is deactivated.
If
Data Set selection
414 = 5, then data set switching is only carried out whenever the frequency
inverter is not released.
The currently selected data set can be read out with Parameter
Active Data Set
249.
Active data set
249 states the activated data set with the value 1, 2, 3 or 4. This is independent of whether the data
set change-over was carried out via control inputs or via
Data Set Selection
414.
1
Statemachine is a standardized software module within the controller of the frequency inverter. The State-
machine represents specified operating states and control within the frequency inverter.
