Eliminated from:
9400 HighLine SW V07.01.06.00
Behaviour of the new version?
The new firmware checks now whether the motor encoder, the load encoder, or the shift factor (C100) has been changed, and only in this case the new settings are accepted in the MCK. Cam data also become invalid in the process so that they need to be revalidated manually by executing the 'Calculate cam data' C2 command.
In all other cases, cam data are not invalidated anymore, not even when the motor parameters are identified.
Which products are affected?
9400 HighLine SW ≤ V07.00.30.00
What happens?
Cam data are becoming invalid, as is reported by an error message on the L_CamProfiler function block. Status -2101345280 is displayed in code C05519 informing the user that the x and y axis data structures as well as the track number are invalid. Additionally, the bError function block output is set to TRUE. If this output is connected to a user error message, the corresponding error will be generated in the controller.
When does the problem occur?
The behaviour occurs if the motor parameters (C00002 = 72) or the inverter characteristic (C00002 = 71) are defined automatically and if the device contains cam data.
Possible diagnostics?
As soon as device command 71 or 72 is activated in code 2, status -2101345280 will be displayed in code C05519 on the L_CamProfiler function block, and the bError function block output will be set to TRUE. Additionally, a logbook entry in the form of a warning will be generated by the firmware irrespective of the set error response of the cam profiler. The warning will disappear automatically after the cam data have been recalculated.
Short-term measures/recommendations?
After defining the motor parameters (C2=72) or the inverter characteristic (C2 = 71), the cam data need to be recalculated using device command 503 in code 2. If the bError function block output is connected to a user error message, it must be set to No response while the motor parameters (C0002 = 72) or the inverter characteristic (C0002 = 71) are defined. After the motor parameters or the inverter characteristic have been defined and the cam data have been recalculated via C00002 = 503, the user error message can be set to the desired response again.
Evaluation
Observing the measures mentioned in Short-term measures/recommendations, the user can define the motor parameters and the inverter characteristic automatically. After being recalculated, the cam data regain validity and pose no restrictions to the user. Faulty movements due to invalid cam data are ruled out.
