What happens?
If an i700 double axis has been updated to an 1700 single axis (or vice versa) the controller signals...
- an exception error.
- 'Synchronization Error'. The CAT bus remains in the 'Pre-Operational state'.
When does the problem occur?
The response described above occurs if an i700 double inverter has been updated to an i700 single inverter (or vice versa) (context menu 'Update device') and the changed project is started on the controller (runtime) afterwards.
Which products are affected?
PLC Designer V3.3
Possible diagnostics?
Check if the corresponding messages can be found in the controller logbook.
Short-term measurements/recommendations?
Do not update to an i700 single inverter but re-insert the double inverter into the project instead and transmit the device parameters of the original device via Export/Import (menu item Project>Device parameters>…) to the single inverter.
Evaluation:
An error message may occur when an i700 double axis is updated to an i700 single axis (or vice versa). The function restriction can be avoided by applying the recommendation mentioned before.
