Check feedback system.

Warning

Memory module is full

The memory module contains too many parameter settings.

Execute "Save user data" 0x2022:003 (P700.03) device command again. This reinitialises the user memory with the current parameter settings. In this way, parameter settings that are no longer required are automatically deleted.

Warning

• The parameter settings were not saved in the memory module.

Memory module not present

The inverter memory module was removed.

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!

Fault

• The default setting stored in the inverter firmware has been loaded.
• The error cannot be reset by the user.

Invalid user data

The user parameter settings in the memory module are invalid.

1. Execute user parameter settings again. 2. Execute device command "Save user data" 0x2022:003 (P700.03).

Fault

• The user parameter settings are lost.
• The default settings were automatically loaded.

Data not compl. saved before powerdown

Saving of the parameter settings was interrupted by an unexpected disconnection.

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).

Warning

• The user parameter settings were not fully saved.
• At the next switch-on, the data stored are copied to the user memory.

Memory module: invalid OEM data

The OEM memory contains invalid parameter settings or is empty.

• Execute device command "Save OEM data" 0x2022:006 (P700.06).
• Thus, the user parameter settings get lost!

Warning

• The user parameter settings were automatically loaded.

Memory module: wrong type

The memory module connected is not supported by the inverter.

1. Switch off inverter. 2. Replace plugged-in memory module by a memory module that matches the inverter. 3. Switch the inverter on again.

Fault

• The default setting stored in the inverter firmware has been loaded.
• The error cannot be reset by the user.

EPM firmware version incompatible

The parameter settings saved in the memory module are incompatible with the firmware version.

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.

Fault

• The data have been loaded into the RAM memory, but they are incompatible.

EPM data: firmware type incompatible

The parameter settings saved in the memory module are incompatible with the firmware type. Example: Memory module of an inverter with an application I/O is used in an inverter with a standard I/O.

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.

Fault

• The data have been loaded into the RAM memory, but they are incompatible.

EPM data: new firmware type detected

The parameter settings saved in the memory module do not match the inverter hardware.

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.

Fault

• The data have been loaded into the RAM memory without being modified, and they are compatible.
• The settings loaded must be accepted by the user (see remedy).

EPM data: PU size incompatible

The parameter settings saved in the memory module are incompatible with the inverter.

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.

Fault

• The data have been loaded into the RAM memory, but they are incompatible.

EPM data: new PU size detected

The parameter settings saved in the memory module comply with a different hardware. Example: Memory module of an inverter with a power of 3 kW is used in an inverter with a power of 18.5 kW.

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.

Fault

• The data have been loaded into the RAM memory without being modified, and they are compatible.
• The settings loaded must be accepted by the user (see remedy).

Invalid parameter changeover configuration

One or more parameters can no longer be used for the "Parameter change-over" function.

1. Check error message for parameter change- over in 0x4047:001 (P756.01). 2. Correct the list entry shown in 0x4047:002 (P756.02).

Warning

• The parameter change-over function is deactivated.

EPM data: unknown parameter found

The memory module contains parameter settings for one or several parameters that are not known to the inverter.

Execute the "Save user data" 0x2022:003 (P700.03) device command. This reinitialises the user memory with the current parameter settings. In this way, parameter settings that are no longer required are automatically deleted.

Information

Parameter changes lost

A voltage failure has occurred and changed parameter settings that had not been saved yet were available.

1. Execute parameter settings again. 2. Execute device command "Save user data" 0x2022:003 (P700.03).
