Switching Over The Inverter Control (Command Data Set) - Siemens SINAMICS G120 Operating Instructions Manual

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: Switchover from automatic to manual operation
A motor is switched on and off and its speed varied either from a central control system via a
fieldbus or from a local control box.
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 known as a command data set.
Example:
Command data set 0: Controlling the inverter via the fieldbus
Command data set 1: Controlling the inverter via terminal strip
