6.1 Parameterisation of frequency inverter SK 2xxE
Every frequency inverter is factory-set for a motor of the same power. All parameters can be adjusted
"online". There are four parameter sets which can be switched over during operation. As delivered, all
parameters are visible; however, some can be hidden with parameter P003.
NOTE
As there are dependencies between parameters, it is possible for invalid internal data and
operating faults to be generated briefly. Only the inactive or non-critical parameter sets should
be adjusted during operation.
As delivered, an external EEPROM ("memory module") is plugged into the frequency inverter. All parameter
changes are made in this plug-in 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 frequency inverter treats the external EEPROM with a higher priority. This means that as son 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).
The individual parameters are combined in various groups. The first digit of the parameter number indicates
the assignment to a menu group:
Menu group No. Master function
Operating displays (P0--): For the selection of the physical units of the display value.
Basic parameters (P1--): Contain the basic inverter settings, e.g. switch on and switch off procedures
and, along with the motor data, are sufficient for standard applications.
Motor data (P2--): Settings for the motor-specific data, important for ISD current control, and
selection of characteristic curve during the setting of dynamic and static boost.
Speed control (P3--): Parameter for the adaptation of any incremental encoder used.
Control clamps (P4--): Analog input and output scaling, specification of digital input and relay output
functions, as well as PI controller parameters.
Extra functions (P5--): Functions dealing with e.g. the BUS interface, pulse frequency or error
acknowledgement.
Positioning (P6--): Adjustment of the positioning function in SK 200E. For further details please
refer to Manual BU 0210.
Information (P7--): Display of e.g. actual operating values, old error messages, equipment status
reports or software version.
Array parameters -01

-xx
Some parameters in these groups can be programmed and read in several
levels (arrays). After the parameter is selected, the array level must also be
selected.
NOTE: Parameter P523 can be used to load the factory settings for all parameters at any time. This
can be helpful, e.g. during the commissioning of a frequency inverter whose parameters no
longer correspond with the factory settings.
ATTENTION
All current parameter settings will be overwritten, if P523= 1 is set and confirmed with "OK".
To save the actual parameter settings, these can be transferred to the ParameterBox memory.
