Switching over the inverter control (command data set)

In several applications, the inverter must be able to be operated from different, higher-level
control systems.
Example: You control the motor either from a central control system, via fieldbus or from a
local control panel.
Command data set (CDS)
This means that you can set the inverter
control in various ways and toggle between
the settings. For instance, as described
above, the inverter can either be operated
via a fieldbus or via the terminal strip.
The settings in the inverter, which are
associated with a certain control type of the
inverter, are called command data set.
You select the command data set using parameter p0810. To do this, you must interconnect
parameter p0810 with a control command of your choice, e.g. a digital input.
Figure 8-4
You obtain the interconnection as in the example above, if you configured the interfaces of
the inverter with p0015 = 7 in the basic commissioning, also see Section Connections and
cables (Page 37).
