5 Parameters
BU 0505 GB-1013 75
5. Parameters
Every frequency inverter is factory-set for a motor of the same power. All parameters can be adjusted
"online". There are four switchable parameter sets available during operation. As delivered, all
parameters are visible; however, some can be hidden with parameter P003.
NOTICE Operating faults
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.
The individual parameters are combined into 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 behaviour
and, along with the motor data, and 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
(SK 520E or higher)
(P3--) Settings for the control parameters (current controller, speed controller, etc.)
with speed feedback.
Control terminals (P4--) Analog input and output scaling, specification of digital input and relay
output functions, as well as PID controller
param eters.
Additional
parameters (P5--) Functions dealing with e.g. the interface, pulse frequency or error
acknowledgement.
Positioning
(SK 52xE and higher) (P6--)
Setting of the positioning function. Details: please refer to BU 0510.
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
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.
All actual parameter settings will be overwritten, if P523= 1 is set and confirmed with "ENTER".
To safeguard the actual parameter settings, these can be transferred to the ControlBox (P550=1) or
ParameterBox memories
