During operation
• The memory module (EPM) is required for operation.
• 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 vol-
tage, e.g. via the X4/24E terminal.
• Parameter settings can be saved manually.
• Parameter settings can be loaded manually.
• Parameter changes can be saved automatically.
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 ≥ V1.0
(downward compatibility).
• Parameters of devices with higher versions are not supported on devices with lower versions.
An error message (PS02/PS03) occurs if the parameter set versions of the two devices are not
compatible.
Saving the parameters in the memory module safe against mains failure
Controller parameter changes via the »Engineer«, the integrated keypad, 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 various opportunities to prevent a data loss by saving the parameter settings in the me-
mory module:
• Quick saving of all parameters at the push of a button
( 23)
• Automatic saving of parameter changes
( 49)
• Manual saving of parameter settings

 Stop!
The memory module must not be plugged in or unplugged during operation.
