Inverter Control
The control of the frequency inverter can, in principle, be carried out using three op-
eration modes. These are set via the data set change-over capable parameter

The Start and Stop command as well as the statement
of the direction of rotation are via digital input signals.

The inverter is controlled by the
Control word.
Only in this control mode are the motion control

Control via
remote digital inputs
(chapter 14.1)
The Start and Stop command as well as the statement
of the direction of rotation are via digital input signals
emulated by the bits of the
Control word.
Parameter
Local/Remote
412 is data set change-over capable. Thus, it is possible to
switch over between the various control modes via the data set selection.
The data set change-over can be carried out locally on the frequency inverter via
digital inputs or via the bus. For data set change-over via the bus, parameter
Data
set selection
414 is used.

With
Data set selection
414 = 0, the data set change-over via digital inputs is active.
If
Data set selection
414 has been set to 1, 2, 3, or 4, the corresponding data set is
activated. Data set change-over via the digital inputs is then disabled.
Via parameter
Active data set
249, the currently selected data set can be read out.
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 digital inputs or
via
Data set selection
414.
