Replacing the controller
• In the event of a device replacement, the entire parameter data of an axis can be copied to the
replacement device by "taking along" the memory module, so that additional PC or diagnosis
terminal operations are not required.
• When replacing the controller, the versions of the old device and the new device are of impor-
tance. Before data are actually transferred, the versions are internally checked. Basically, the fol-
lowing applies:
• Parameter sets of old devices with V 1.0 can be processed on new devices ≥ V 1.0
(downward compatibility).
• Parameters of devices with higher versions are not supported on devices with lower versions.
An error message will be issued if the parameter set versions of the two devices are not com-
patible.
Saving the parameters in the memory module safe against mains failure
Controller parameter changes via the »Engineer«, the diagnosis terminal, or a master control via
fieldbus communication will be lost after mains switching of the controller unless the settings have
been explicitly saved.
You have several options to avoid data loss by saving the parameter sets in the memory module:
• Automatic saving of parameter changes ( 64)
• Manual saving of parameter settings ( 64)
Parameter set transfer using the »Engineer«
When an online connection to the controller has been established, the following transfer functions
can directly be executed via the Toolbar or the Online menu using the L-force »Engineer«:

Tip!
Detailed information on parameter set transfers using the »Engineer« can be found in the
»Engineer« online help.
