8400 StateLine, HighLine and TopLine: FW version = 13.00.00.00
Response of the new version?
The setting in C2314/1 has no impact anymore. The value in C653/1 Sensitivity of the setpoint feedforward control is also maintained when a parameter download is carried out.
Which products are affected?
8400 StateLine, HighLine and TopLine: FW version ≤ 13.00.00.00
What happens?
After a parameter download, the setting of the Sensitivity of the setpoint feedforward control is evidently reset to C653/1=0: Inactive.
When does the problem occur?
After a parameter download from the PC or from a control, C653/1 is overwritten with the value from C2314/1.
Internally both codes are linked to one variable.
Diagnostics options?
The response can for instance be observed after every 'Download parameter set' action from the Engineer if C653/1 <> C2314/1 has been set.
Short-term measures/recommendations?
Set the parameters C653/1 and C2314/1 to the same value.
Evaluation:
Unequal values in the two parameters are generated by an offline change of a parameter. If a parameter is changed online, the response does not occur. The value that is stored is also active again after mains switching. The relationship is difficult to spot. The setting of the parameter has an impact on the quality of the torque feedforward control.
