Data handling

In the following, the behaviour of the inverter is described if the data on the memory module
do not match the inverter hardware or firmware, for whatever reason.
The following points are described in detail here:
Automatic loading of the parameter settings when the inverter is switched on
•
Manual loading of the user data via device command
•
Manual loading of the OEM data via device command
•
Manual saving of the parameter settings via device command
•
Hardware and firmware updates/downgrades
•
Automatic loading of the parameter settings when the inverter is switched on
Process when the inverter is switched on:
1. The default setting saved in the inverter firmware is loaded.
2. If a memory module with valid data is available, the data is loaded from the user memory.
Otherwise a corresponding error message is output:
Error message Info
0x7681: No memory The default setting saved in the inverter firmware is loaded. The error cannot be reset by the user.
module
Remedy:
1. Switch off inverter.
2. Plug the memory module into the inverter.
3. Switch the inverter on again.
Note: The memory module cannot be replaced during ongoing operation!
0x7682: Memory mod- The user parameter settings in the memory module are invalid. Thus, the user parameter settings get lost. The default
ule: invalid user data setting is loaded automatically.
Remedy:
1. Execute user parameter settings again.
2. Execute device command "Save user data"
0x7684: Data not com- Saving the parameter settings was interrupted by an unexpected disconnection. The user parameter settings were not
pletely saved before saved completely. When the inverter is switched on the next time, the backup data is copied to the user memory.
switch-off
Remedy:
1. Check user parameter settings. (The loaded backup is an older version.)
2. If required, repeat the changes made last.
3. Execute device command "Save user data"
0x7689: Memory mod- The OEM memory contains invalid parameter settings or is empty. The user parameter settings are loaded automatically.
ule: invalid OEM data
Remedy:
• Execute device command "Save OEM data"
• Thus, the user parameter settings get lost!
Notes:
If the memory module contains invalid data, the device commands "Load user data"
