2.3.3 Save parameter settings in the memory module safe against mains failure
Inverter 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 inverter
• 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 inverter.
• Full functionality of the memory module is even provided if the power supply has been switched
off and only the electronic components of the inverter 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.
