The relevant parameters for the device are described in the following. The parameters are accessed
using a parameterization tool (e.g. NORDCON- software or control and parameterization unit, see also
(

Section 3.1.1 "Use of control and parameterization units") and therefore makes it possible to adapt
the device to the drive task in the best possible way. Different device configurations can result in
dependencies for the relevant parameters.
The parameters can only be accessed if the control unit of the device is active.

SK 2x5E type devices must be provided with a 24 V DC control voltage to do this (

Section 2.3.3
"Electrical connection of the control unit").
SK 2x0E type devices must be equipped with a power supply that generates the 24 V DC control
voltage required for this purpose by applying the line voltage (

Limited adaptations of individual functions of the relevant devices can be implemented via
DIP - switches. Access to the parameters of the device is essential for all other adaptations.
It should
be noted that hardware configurations (DIP - switches) have priority over configuration via
software (parameterization).
Every variable frequency drive is factory-set for a motor of the same power. All parameters can be
adjusted online. Four switchable parameter sets are available during operation. The scope of the
parameters to be displayed can be changed through supervisor parameter
P003
.
Information
Incompatibility
In the software change of version V1.2 R0 of the variable frequency drive, the structure of individual parameters
was modified for technical reasons.
(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 plugging an EEPROM (memory module) from a variable frequency drive with an earlier software version
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
above into a variable frequency drive with a previous software version since this would lead to loss of all
data.
As delivered, an external EEPROM (memory module) is plugged into the variable frequency drive.
The following applies up to firmware version V1.4 R1:
All parameter changes are made in the plug-in (external) EEPROM. As of firmware version 1.3, an internal
EEPROM is automatically activated for data management if the plug-in EEPROM is removed. Parameter changes
therefore affect the internal EEPROM.
The variable frequency drive treats the external EEPROM with a higher priority. This means that as soon as an
external EEPROM (memory module) is plugged in, the dataset of the internal EEPROM is concealed.
The datasets can be copied between the internal and the external EEPROM (P550).
