Saving/loading the parameter settings

If parameter settings of the inverter are changed, these changes at first are only made in the RAM memory of the inverter. In order to save the parameter settings with mains failure protection, the inverter is provided with a pluggable memory module and corresponding device commands.
 
Details
The memory module is provided with two memories, the user memory and the OEM memory.
 
User memory
The user memory is used as power-failure-proof storage of parameter settings made by the user during commissioning/operation.
–
The SET display blinks on the keypad if a parameter setting has been changed but has not been saved in the memory module with mains failure protection. In order to save parameter settings in the user memory of the memory module, press and hold the enter key for longer than 3 s.
 
–
Parameter settings carried out with »EASY Starter« or via network must be explicitly saved in the user memory by means of the "Save user data" device command, so that the changes carried out are not lost when the mains of the inverter are switched.
 
–
Saving can also be made in the »EASY Starter« via the button or the <F6> function key.
 
–
The device command "Load user data" serves to reload the data from the user memory into the RAM.
 
 
OEM memory
The OEM memory is provided for the storage of customised parameter settings by the OEM/ engineer. If the user carries out parameter settings with the keypad, they are always saved in the user memory if the enter key is pressed and held for longer than 3 s. The OEM memory remains unaffected by these changes.
–
With the "Load OEM data" device command, the parameter settings preconfigured by the OEM/ engineer can be reloaded to the RAM memory of the inverter at any time if required.
 
–
For saving parameter settings in the OEM memory, the "Save OEM data" device command must be executed explicitly. The parameter settings are simultaneously saved in the user memory.
 
 
Response after initial switch-on of the inverter
After switch-on, the inverter first tries to load the parameter settings stored in the user memory. If the user memory is empty or damaged, an error message is output and the user must intervene:
–
Case 1 = user memory empty: → default setting is loaded automatically from the firmware → data are saved automatically in the user memory of the memory module.
 
–
Case 2 = user memory damaged: → Error message → default setting is loaded automatically → data are saved automatically in the user memory of the memory module.
 
–
Case 3 = OEM memory empty/damaged: → error message → data are loaded automatically from the user memory of the memory module.

(Device commands: Save user data)
1 = save current parameter settings in the user memory of the memory module with mains failure protection.
–
This process may take some seconds. When the device command has been executed successfully, the value 0 is shown.
 
–
Do not switch off the supply voltage during the saving process and do not unplug the memory module from the device!
 
–
When the device is switched on, all parameters are automatically loaded from the user memory of the memory module to the RAM memory of the device.

–
Loading parameters has a direct effect on the cyclic communication: The data exchange for control is interrupted and a communication error is generated.
