Switching Over The Inverter Control (Command Data Set) - Siemens SINAMICS G120D Series Operating Instructions Manual

7.2.4

Switching over the inverter control (command data set)

In some applications, it must be possible to switch over the master control for operating the
inverter.
Example: The motor is to be operable either from a central control via the fieldbus or from a
local control box via the terminal strip.
Command data set (CDS)
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 the terminal strip.
The settings in the inverter, which are as-
signed to a specific master control, are termed
the 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.
