Save parameter settings in the memory module safe against mains failure

Controller parameter changes via the EASY Starter /»Engineer«, the keypad, or a master
control via fieldbus communication will be lost after mains switching of the controller
unless the settings have been explicitly saved to the integrated memory module.
General information
 In the delivery state, the Lenze setting of the following parameters has been saved to
the integrated memory module:
– the parameters of the controller
– the parameters of the communication module plugged into the MCI interface
– the parameters of the possibly existing safety module (device variant)
 When the device or the external 24 V voltage supply is switched on, all parameters are
automatically loaded from the memory module into the main memory of the
controller.
 Full functionality of the memory module is even provided if the power supply has been
switched off and only the electronic components of the controller are externally
supplied by a 24 V DC voltage, e.g. via the X4/24E terminal.
 The memory module can be preconfigured with customer-specific data.
 The memory module is available as a spare part - without any data.
During operation
 Parameter sets can be saved and loaded manually.
 Using the keypad, you can press function key
 The »EASY Starter«/»Engineer« serves to execute the saving via the icon
toolbar or via the device command "Save all parameter sets"
start").
– The storage process may take a couple of seconds. After the device command has
been called in C00002/11, dynamic status information ("Work in progress 20%" 
"Work in progress 40%"  "Work in progress 60%", etc.) is returned.

Note!
In order to prevent data inconsistencies during the saving process:
• Do not switch off the supply voltage!
• Do not remove the memory module from the device!
Automatic saving of changed parameter settings is explicitly not supported
because this significantly reduces the service life of the memory module.
Unplugging the memory module
The memory module is hot-pluggable. A removal during operation causes a warning
