Behavior of the new version:
Description of the behavior:
The firmware update of Lenze inverters is not completed.
At i550 the keypad is showing KP.ERROR

The logbook of Controller is showing one or more of these failure messages:


Conditions under which the behavior occurs:
A firmware update is being carried out on the i550 from firmware version 7.5. At ECAT, there are several other devices on which firmware updates are being carried out at the same time.
Affected products:
Cabinet Controller c430
Cabinet Controller c520
Cabinet Controller c550
Short-term measure, recommendations, evaluation:
All drives, except the i550 V7.5, should be connected to EtherCAT. The update can then be carried out via a new, empty PLC project for the controller (only for EtherCAT configurations).
All i550 V7.5 drives must be updated manually using the EASY Firmware Loader and a USB connection.
If the error “KP.ERROR” is displayed on the i550 drive (particularly with FW V6.x), the device must be updated manually using the EASY Firmware Loader and a USB connection.
