A copy function is available making it easier to commission more than one command data
set.
Table 7- 45 Parameters for copying the command data sets
Parameter
Description
P0809[0]
Number of the command data set to be copied (source)
P0809[1]
Number of the command data set to which the data is to be copied (target)
P0809[2] = 1
Start copying
Once the data has been copied, p0809[2] is automatically set to 0
Example
P0809[0] = 0
P0809[1] = 1
P0809[2] = 1
The parameters of command data set 0 are copied to command data set 1
7.11.2
Switching over drive data sets (different motors connected to an inverter)
When the drive's properties change, the inverter's parameterization must be changed.
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 four
different ways:
1.
Setpoint sources
(exceptions: Analog inputs and fieldbus)
2.
Setpoint processing
3.
Motor control
4.
Motor and inverter protection
5.
Technological functions
(Exception: Technology controller, brake control, automatic restart and unassigned
function blocks)
The associated parameters are indexed (index 0, 1, 2 or 3). Control commands select one of
the four indices and therefore one of the four 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.
The term "command data set" is used to indicate all of the switchable parameters of the five
functions mentioned above with the same index.
