2.2 List of parameters
Notice: The Control Unit power supply may only be powered down after data has been saved (i.e. after data save has been
started, wait until the parameter again has the value 0).
Writing to parameters is inhibited while saving.
The progress while saving is displayed in r3996.
Note: Parameters saved with p0977 = 10, 11 or 12 can be downloaded again with p0976 = 10, 11 or 12.
Identification and maintenance data (I&M data, p8806 and following) are only saved for p0977 = 1.
p0978[0...n] List of drive objects / List of the DO
CU_DCP Can be changed: C1(1)
Data type: Unsigned8
Min
0
Description: This parameter is an image of p0101 in conformance with PROFIdrive.
Parameters p0101 and p0978 contain the following information:
1) The same number of drive objects
2) The same drive objects
In this sense, they are consistent.
Difference between p0101 and p0978:
p0978 can be re-sorted and a zero inserted in order to identify those drive objects that participate in the process data
exchange and to define their sequence in the process data exchange. Drive objects that are listed after the first zero,
are excluded from the process data exchange.
For p0978, in addition, the value 255 can be inserted a multiple number of times.
p0978[n] = 255 means: The drive object is visible for the PROFIBUS master and is empty (without any actual process
data exchange). This allows cyclic communications of a PROFIBUS master with unchanged configuring to the drive
units with a lower number of drive objects.
Dependency: Refer to: p0101, p0971, p0977
Note: p0978 cannot be changed when the drive system is first commissioned. The reason for this is that at this time the
actual topology has still not been acknowledged (p0099 is still not equal to r0098 and p0009 is set to 0).
r0980[0...299] List of existing parameters 1 / List avail par 1
All objects Can be changed: -
Data type: Unsigned16
Min
-
Description: Displays the parameters that exist for this drive.
Dependency: Refer to: r0981, r0989
Note: The existing parameters are displayed in indices 0 to 298. If an index contains the value 0, then the list ends here. In
a long list, index 299 contains the parameter number at which position the list continues.
This list consists solely of the following parameters:
r0980[0...299], r0981[0...299] ... r0989[0...299]
The parameters in this list are not displayed in the expert list of the commissioning software. However, they can be
read from a higher-level control system (e.g. PROFIBUS master).
r0981[0...299] List of existing parameters 2 / List avail par 2
All objects Can be changed: -
Data type: Unsigned16

-
Description: Displays the parameters that exist for this drive.
Dependency: Refer to: r0980, r0989
