13.11 Behaviour of the inverter in case of incompable data in the memory module
Below you will nd a descripon of the inverter behaviour when the data on the memory
module does not match the inverter hardware or rmware.
The following points are described in detail here:
•
Automac loading of the parameter sengs 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 sengs via device command
•
Hardware and rmware updates/downgrades
Automac loading of the parameter sengs when the inverter is switched on
Process when the inverter is switched on:
1.
The default seng saved in the inverter rmware 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: Memory mod-
ule not present
The default seng saved in the inverter rmware is loaded. The error cannot be reset by the user.
Remedy:
1.
Switch o inverter.
2.
Plug the memory module into the inverter.
3.
Switch the inverter on again.
Note: The memory module cannot be replaced during ongoing
operaon!
0x7682: Memory mod-
ule: Invalid user data
The user parameter sengs in the memory module are invalid. Thus, the user parameter sengs get lost. The default
seng is loaded automacally.
Remedy:
1.
Execute user parameter sengs again.
2.
Execute device command "Save user data" 0x2022:003 (P700.03).
0x7684: Data not
compl. saved before
powerdown
Saving the parameter sengs was interrupted by an unexpected disconnecon. The user parameter sengs were not
saved completely. When the inverter is switched on the next me, the backup data is copied to the user memory.
Remedy:
1.
Check user parameter sengs. (The loaded backup is an older version.)
2.
If required, repeat the changes made last.
3.
Execute device command "Save user data" 0x2022:003 (P700.03).
0x7689: Memory mod-
ule: invalid OEM data
The OEM memory contains invalid parameter sengs or is empty. The user parameter sengs are loaded automacally.
Remedy:
•
Execute device command "Save OEM data" 0x2022:006 (P700.06).
•
Thus, the user parameter sengs get lost!
Notes:
•
If the memory module contains invalid data, the device commands "Load user data"
0x2022:004 (P700.04) and "Load OEM data" 0x2022:005 (P700.05) are not executed. The
status feedback "Acon cancelled" takes place.
•
If the memory module is empty, the default seng saved in the inverter rmware is loa-
ded. No acon is required by the user. The memory module remains empty unl the
device command "Save user data" 0x2022:003 (P700.03) or "Save OEM data" 0x2022:006
(P700.06) is executed.
•
Irrespecve of the data on the memory module, the device command "Load default set-
tings" 0x2022:001 (P700.01) is always enabled.
Manual loading of the user data via device command
Device command: "Load user data" 0x2022:004 (P700.04)
•
If the user memory contains invalid parameter sengs, the default seng saved in the
inverter rmware is automacally loaded.
•
For possible error messages, see the table above.
