4.3.3 Plug-in EEPROM ("Memory Module")
The frequency inverter is equipped with an internal EEPROM and a plug-in EEPROM ("Memory
Module") which operates in parallel to this for the storage and management of parameter data. The
data from the device are managed in parallel on both devices, so that a safe and rapid exchange of
parameter settings in the device is possible for commissioning or in case of service.

4.3.3.1 Replacing the plug-in EEPROM ("Memory Module")
A decisive advantage in case if servicing of the SK 2xxE is necessary is the simple transfer of data
from the failed frequency inverter to the replacement device. However, the following must be noted for
the exchange of data via the plug-in EEPROM:
• The data transfer must be deliberately activated ( section 4.3.3.2 "Copy function").
• Any restrictions which exist due to the change between devices from different generations must be
noted.
The plug-
in EEPROM is located on the
underside of the device.
Access to the EEPROM is enabled by removing
the defective frequency inverter (2) from the
connection unit (1). The EEPROM is unlocked
by lightly pressing the short sides together and
then pulling it out.
The EEPROM must be inserted into the new
device. The EEPROM is correctly seated when
the lock audibly engages. It is not possible to
insert the EEPROM so that it is laterally
reversed.

Devices with hardware version "EAA" and above have a more powerful processor than devices from
the 1st. Generation (hardware version "AAA"). This includes a larger range of functions, e.g. integrated
PLC functionality (SPS function) and operation of PMSMs.
In order to manage the larger amount of data, the capacity of the plug-in
EEPROM
("Memory Module") has been extended. EEPROMs with the
larger memory capacity can be identified from an additional raised marking
("II") on the housing.
Alternatively, an adhesive label with "V2" may be
applied.
