What happens?
For some Lenze drive controllers (i700 servo inverter, i550 frequency inverter), the controller supports firmware downloads via EtherCAT. When selecting a different firmware version on the drive controller's 'Firmware' tab in the PLC Designer and transferring the PLC project to the controller, the drive controller's firmware version does not change.
When does this behaviour occur?
The behaviour occurs when logging in to the controller after changing the firmware version on the drive controller's 'Firmware' tab by using the PLC Designer and confirming the 'Field device parameters have changed' dialog with <Download All> .
Which products are affected?
PLC Designer V3.3.2 and higher
Short-term measures:
After downloading the project, create a boot project and restart the controller.
Evaluation/recommendation:
After changing the firmware version of a drive controller in the PLC project and downloading the project to the controller, the changed firmware is not automatically transferred from the controller to the drive controller. An applicative solution is described under 'Short-term measures'.
