Behaviour of the inverter in case of incompatible data in the memory module

Below you will find a description of the inverter behaviour when the data on the memory module does not match the inverter hardware or firmware.

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: Memory module not present	The default setting saved in the inverter firmware is loaded. The error cannot be reset by the user. 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: Invalid user data	The user parameter settings in the memory module are invalid. Thus, the user parameter settings get lost. The default setting is loaded automatically. Remedy: 1. Execute user parameter settings again. 2. Execute device command "Save user data" 0x2022:003 (P700.03).
0x7684: Data not compl. saved before powerdown	Saving the parameter settings was interrupted by an unexpected disconnection. The user parameter settings were not saved completely. When the inverter is switched on the next time, the backup data is copied to the user memory. 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" 0x2022:003 (P700.03).
0x7689: Memory module: invalid OEM data	The OEM memory contains invalid parameter settings or is empty. The user parameter settings are loaded automatically. Remedy: – Execute device command "Save OEM data" 0x2022:006 (P700.06). – Thus, the user parameter settings 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 "Action cancelled" takes place.

–

If the memory module is empty, the default setting saved in the inverter firmware is loaded. No action is required by the user. The memory module remains empty until the device command "Save user data" 0x2022:003 (P700.03) or "Save OEM data" 0x2022:006 (P700.06) is executed.

–

Irrespective of the data on the memory module, the device command "Load default settings" 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 settings, the default setting saved in the inverter firmware is automatically loaded.

–

For possible error messages, see the table above.

Manual loading of the OEM data via device command

Device command: "Load OEM data" 0x2022:005 (P700.05)

–

If the OEM memory contains invalid parameter settings, the user parameter settings are loaded automatically.

–

If the OEM memory is empty, the status feedback "Action cancelled" takes place. The current parameter settings remain unchanged.

Manual saving of the parameter settings via device command

Device command: "Save user data" 0x2022:003 (P700.03)

–

It may happen that the parameter settings cannot be saved because the user memory is full. In this case, the following error message appears:

Error message	Info
0x7680: Memory module is full	The memory module contains too many parameter settings. The parameter settings were not saved in the memory module. Remedy: Execute device command "Save user data" 0x2022:003 (P700.03) again. This reinitialises the user memory with the current parameter settings. By this means, parameter settings no longer required are deleted automatically.

Hardware and firmware upgrades/downgrades

By "taking along" the memory module, all parameter settings of a device can be transferred to another device, for instance, in case of a device replacement. When switched on, the inverter checks whether the parameter settings saved in the memory module match the inverter hardware and firmware. In case of an incompatibility, a corresponding error message is output.

The following table contains details on different scenarios:

Prio	Compatibility check User data ßà device	Error message	Info
1	Device has a newer firmware Example: Version 2.x à version 3.x	-	The "firmware upgrade" is recognised. – The user parameter settings are loaded without an action being required by the user. – If the parameter settings are saved afterwards, the user memory is reinitialised with the current parameter settings. By this means, parameter settings no longer required are deleted automatically.
1	Device has an older firmware Example: Version 4.x à version 3.x	0x7690: EPM firmware version incompatible	The data is loaded into the RAM memory but are incompatible. Remedy: 1. Execute device command "Load default settings" 0x2022:001 (P700.01). 2. Execute "Save user data" 0x2022:003 (P700.03) or "Save OEM data" 0x2022:006 (P700.06) device command.
2	Firmware type is different	0x7691: EPM data: firmware type incompatible
	Power unit is different (and incompatible with saved data)	0x7693: EPM data: PU size incompatible
	Country code is different Example: EU à USA	0x7691: EPM data: firmware type incompatible
	Device has less functionality Examples: i550 à i510 Application I/O à Standard I/O	0x7691: EPM data: firmware type incompatible
3	Network option is different Example: CANopen à PROFIBUS	0x7692: EPM data: new firmware type detected	The data is loaded into the RAM memory and is compatible. However, the settings must be accepted by the user: 1. Check parameter settings. 2. Reset error. 3. Execute "Save user data" 0x2022:003 (P700.03) or "Save OEM data" 0x2022:006 (P700.06) device command.
4	Device has more functionality Examples: i510 à i550 Standard I/O à application I/O	-	The "hardware upgrade" is recognised. – The user parameter settings are loaded without an action being required by the user. – If the parameter settings are saved afterwards, the user memory is reinitialised with the current parameter settings. By this means, parameter settings no longer required are deleted automatically.
5	Power unit is different (but compatible with saved data) Example: 230 V/0.75 kW à 400 V/5.5 kW	0x7694: EPM data: new PU size detected	The data is loaded into the RAM memory and is compatible. However, the settings must be accepted by the user: 1. Check parameter settings. 2. Reset error. 3. Execute "Save user data" 0x2022:003 (P700.03) or "Save OEM data" 0x2022:006 (P700.06) device command.
