Eliminated from:
9400 HighLine SW V08.00.24.00
Behaviour of the new version?
Motor parameter identification - which was based on a voltage-controlled process and which led to useless results or was even cancelled in the case of greater designs - has now been turned into a current-controlled process.
The current controller parameterisation required for the modified identification process is carried out automatically by an upstream process for current controller parameterisation by default.
Another advantage of the new process is that asynchronous machines do not experience any motion on the motor shaft during the identification run anymore. Synchronous motors only experience a single compensating movement at the beginning of the identification run which serves to move to the electric zero position.
The motor parameter identification for special motors can be carried out by adjusting service code C02866 and selecting the current controller parameterisation provided in codes C75 / C76.
Due to a combination of the measures, two function restrictions could be eliminated. Safe motor parameter identification is also possible for greater designs.
<hr>
Which products are affected?
9400 HighLine SW ≤ V07.01.06.00, with rated currents from 245 A onwards (E94ASxE2454 - E94ASxE6954)
What happens?
An error message is displayed.
When does the problem occur?
The problem can occur during motor parameter identification (C00002 = 72).
Possible diagnostics?
Check whether an error occurs during motor parameter identification (error message in Engineer).
Short-term measures/recommendations?
The motor must be parameterised based on the data sheet from the manufacturer. Enter the values from the data sheet into the corresponding codes.
Evaluation:
The problem only occurs during commissioning and can be avoided by using the workaround mentioned above.
