6.7 Switching over the drive control (command data set)

6.7 Switching over the drive control (command data set)
Several applications require the option of switching over the control authority to operate the
inverter.
Example: The motor is to be operable either from a central control via the fieldbus or via the
local digital inputs of the inverter.
Command data set (CDS)
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 6-16
As in the example above, you obtain the interconnection if you configured the interfaces of
the inverter with p0015 = 7 in the basic commissioning, also see section
and cables (Page 51).

Example for the various command data sets
This means that you can set the inverter con-
trol in various ways and toggle between the
settings. For instance, as described above,
the inverter can either be operated via a
fieldbus or via its digital inputs.
The settings in the inverter, which are as-
signed to a specific master control, are termed
the command data set.
