2.3.3 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 parameters has been saved to the integrated
memory module. These parameters are
• 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 customised 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
 to save the parameter settings.
• The »EASY Starter«/»Engineer« serves to execute the saving via the icon in the toolbar or via
the device command "Save all parameter sets" ( C00002/11 = "1: On / 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.
