NORDAC FLEX (SK 200E ... SK 235E) – Users Manual for Frequency Inverters

BU 0200 en-US-4920
The following applies as of firmware version V1.4 R2:
All parameter changes are made in the internal EEPROM. If an external EEPROM has been connected, all
changes are automatically stored on this as well. The external EEPROM therefore acts as an additional data
backup. Parameter P550 can be used to transfer data from the external EEPROM to the internal EEPROM (e.g.
during the data transfer between different devices of the same type). It is also possible to trigger the copying
procedure using DIP switches (
Section 4.3.2.2 "DIP switches (S1)").
The relevant parameters for the device are described below. Please refer to the respective
supplementary manuals for explanations for parameters which concern the field bus options or the
special functionality of the POSICON, for example.

Information
Factory setting P523
The factory settings of the entire parameter set can be loaded at any time using parameter
P523
. For
example, this can be useful during commissioning if it is not known which device parameters have
been changed earlier and could have an unexpected influence on the operating behavior of the drive.
The restoration of the factory settings (
P523
) normally affects all parameters. This means that all
motor data must subsequently be checked or reconfigured. However, parameter
P523
also provides a
facility for excluding the motor data or the parameters relating to bus communication when the factory
settings are restored.
It is advisable to back up the present settings of the variable frequency drive beforehand.
