Up to firmware version 1.4 R1 data was backed up in the pluggable EEPROM. The EEPROM then
had to remain plugged in during operation.
In the simplest configuration for SK 2x0E, size 4 and the SK 2x5E units, even without the plugged-in
EEPROM, all important parameters can be set using two potentiometers and eight DIP switches.
LEDs are provided for operating status diagnostics. The use of a control module is therefore not
absolutely necessary.
Information
With the software version change from V1.1 R1 to V1.2 R0 of the variable frequency drive, the structure of
individual parameters was changed (Section 5 "Parameter"), e. g.: up to version V 1.1 R2 (P417) was a single
parameter, but from version V1.2 R0 it was subdivided into two arrays ((P417) [-01] and [-02]).
When an EEPROM from a variable frequency drive with an earlier software version is plugged into a variable
frequency drive with software version V1.2 or higher, the stored data is automatically converted to the new format.
New parameters are stored with the default setting. This therefore provides correct functionality.
However, it is not permissible to plug in an EEPROM (memory module) with a software version of V1.2 or
higher into a variable frequency drive with a previous software version since this would lead to loss of all
data.
Information
The functional assignment of DIP switch S1-6 was changed in the software version change from V1.4 R1 to V1.4
R2 of the variable frequency drive ( Section 4.3.2.2 "DIP switches (S1)"). The U/F function (changeover
between ISD control and the U/F characteristic) was replaced with the COPY function (triggering of data
exchange from the external EEPROM (memory module) to the internal EEPROM).
