Changing over the command data sets (manual, automatic)

Switching operating priority
In some applications, the inverter is operated from different locations.
Example: Switchover from the automatic mode into the manual mode
A central control can switch a motor on/off or change its speed either via a fieldbus or via
local switches. A key-operated switch close to the motor can be used to switch the operating
priority of the inverter from "control via fieldbus" to "local control".
Command data set (CDS)
The inverter offers options to parameterize the settings for the command sources, setpoint
sources and status messages (with the exception of analog outputs) in three different ways.
The associated parameters are indexed (index 0, 1 or 2). When the inverter is operational,
control commands select one of the three indices and therefore one of the three settings that
has been saved. This means that as described in the example above, the master control of
the inverter can be switched over.
All of the switchable parameters for command sources, setpoint sources and status
messages with the same index is known as a "command data set".
