Eliminated from:
9400 HighLine SW V10.00.12.00
9400 ServoPLC SW V04.00.12.00
Behaviour of the new version?
The auto increment function is only effective when writing code C02925. As a result, it is possible to transfer a new profile from a PLC into the drive controller and at the same time the user can be online with the Engineer and look at code C02925.
What happens?
If the auto increment function was activated the interpolation point number was also incremented when reading code C02925 (y value).
When does the problem occur?
In order to select profiles via the parameter channel the 'Auto increment' function of the interpolation point number can be activated in the drive controller.
As a result, it is only required to write the x and y values of the interpolation points.
The interpolation point is automatically incremented by the drive controller when code C02925 (y value) is written and does not have to be written separately from outside.
If the user is online with the Engineer and code C02925 is indicated the increment function is also carried out without writing the y value.
This behaviour stops a PLC from writing a profile into the drive controller at the same time.
Which products are affected?
9400 HighLine SW ≤ V09.00.09.00
9400 ServoPLC SW <= V03.00.17.00
Possible diagnostics?
Check of the y values in C02925
Short-term measures/recommendations
Transfer the profile without read access to code C02925 via Engineer.
Evaluation:
The behaviour occurs during commissioning and can be avoided as described before.
