Changing over drive data sets (several motors connected to a frequency inverter)
Switching motor control
In certain applications, the inverter parameters need to be switched.
Example:
One inverter is to 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 offers up to three different methods for parameterizing various functions and for
switching between these different settings. The parameters for these functions are indicated
with the index numbers 0, 1, and 2. Control commands define the switchover between the
parameters by selecting one of these three indices.
The total of all switchable parameters with the same index is known as a "drive data set".
Since all the switchable parameters have the same three indices (0, 1, and 2), the functions
can only be switched together.
The following diagram shows which functions can be switched.
