NORDAC FLEX (SK 200E ... SK 235E) – Users Manual for Frequency Inverters
Downward compatibility:
In principle, it is permissible to operate older-generation variable frequency drives with an EEPROM
from a newer generation and vice versa.
Please note:
Before the exchange of data, in addition to the firmware status (software versions) of the two variable
frequency drives, it is also necessary to compare the hardware versions of the variable frequency
drives and the EEPROMS, because:
– Variable Frequency Drives with the hardware status "EAA" can only read data from a first
generation EEPROM (EEPROM without label). The EEPROM cannot be written by the variable
frequency drive so that parameter changes are only saved in the device itself and are no longer
saved in the EEPROM.
– Variable Frequency Drives with the hardware status "AAA" can read and write data from a
second generation EEPROM (EEPROM with label). However, only data saved on the EEPROM
which can be processed by the variable frequency drive due to its older construction status is
used (incompatibility).
Information
During the transfer of data records between devices with different firmware statuses (software versions) in which
the replacement device has an older status than the defective device, incompatibilities between individual
functions may occur. Because of this, we recommend that the firmware be updated to the currently available
software status for the device generation.
After the data transfer we recommend that the EEPROM included in the scope of delivery of the
device be re-inserted in the replacement device and data from the device be copied to the EEPROM.

Copy function
The copy function is located in parameter P550 and is described in detail in the manual. In addition, a
copy function is available, which is triggered independently from parameter P550, simply by setting a
DIP switch.

Copy function DIP switches S1 – 6 "COPY"
Transferring data from the external to the internal EEPROM has been made even simpler through the
new function of the DIP switch element S1-6 ("COPY").
If a 0 1 flank is detected on DIP switch element S1-6 when the variable frequency drive is restarted,
copying of data from the plug-in EEPROM to the internal EEPROM is triggered.
The copying process takes several seconds. During the copying process, the status LED rapidly
flashes red-green alternately.
•
If an error is detected during copying of data, the process is interrupted and an error message
(E008.2 "External copying error") is generated.
•
If no plug-in EEPROM is detected (not available or defective), the process is interrupted and an
error message (E008.2 "External copying error") is generated.
•
Interruption of data transfer, e.g. due to premature switch-off of the line voltage or the control
voltage of the inverter, interrupts the copying process. No error message is generated! The
interruption can only be identified by checking the parameter settings of the variable frequency
drive.
If necessary, the copying process must be repeated.
