Changing over drive data sets

Switching motor control
In certain applications, the inverter parameters need to be switched.
Example: Operating different motors on one inverter
One inverter should operate one of two different motors. Depending on which motor is to run
at any given time, the motor data and the ramp-function generator times for the different
motors must be adjusted accordingly in the inverter.
Drive data sets (DDS)
The inverter provides the possibility of parameterizing the following functions in up to three
different ways:
● Setpoint sources
(exceptions: Analog inputs and fieldbus)
● Setpoint calculation
● Motor control
● Motor and inverter protection
● Technological functions
(Exception: Technology controller, brake control, automatic restart and unassigned
function blocks)
The associated parameters are indexed (index 0, 1 or 2). Control commands select one of
the three indices and therefore one of the three saved settings.
This means, that as described in the example above, you can switch over all of the settings
of the inverter matching the particular motor.
All of the switchable parameters of the five functions mentioned above with the same index
is known as a "command data set".
