7 Parameterisation
There are four switchable parameter sets available during operation. All parameters are always visible. All
parameters can be adjusted "online".
Note::
As there are dependencies between the parameters, it is possible for invalid internal data and
operating faults to be generated temporarily. Only inactive parameters should be adjusted during
operation.
The individual parameters are combined in various groups. The first digit of the parameter number indicates its
assignment to a menu group.
The following main functions are assigned to the menu groups:
Menu group No. Master function
Operating displays (P0--): For the selection of the physical units of the display value.
Basic parameter (P1--): Contain the basic inverter settings, e.g. switch on and switch off
procedures and, along with the motor data, and are sufficient for
standard applications.
Motor data / characteristic
curve parameters
(P2--):
Setting of the motor-specific data, important for the ISD current control
and choice of the characteristic curve during the setting of dynamic
and static boost.
Control clamps (P4--): Analog input and output scaling, specification of digital input and relay
output functions, as well as PID controller parameters.
Extra functions (P5--): Functions dealing with e.g. the interface, pulse frequency or error
acknowledgement.
Information (P7--): For display of e.g. actual operating modes, old error messages, device
status reports or software version (read parameter).
Array parameters -01
…
-xx
Some parameters can also be programmed or read out in several
levels (arrays). After selection of the parameter, 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 lost, if P523= 1 is set and confirmed with "ENTER".
To safeguard the actual parameter settings, these can be transferred to the ControlBox or
ParameterBox memories.
