9 Machine Data
The input of the machine data is the foundation for the functionality of the control
functions and methods. In the course of the guided commissioning, the necessary
parameters are inquired according to the selected
Configuration
30.
9.1 Rated Motor Parameters
Set the rated parameters of the three-phase asynchronous machine according to the
rating plate or the data sheet of the motor. The default settings of the machine pa-
rameters are based on the nominal data of the frequency inverter and the corres-
ponding four-pole three-phase motor. The machine data required for the control
functions and methods are checked for plausibility and calculated in the course of the
commissioning.
The user should check the rated values specified by default.

In the case of three-phase machines, the speed can be increased at a constant tor-
que if the motor winding can be switched over from star to delta connection. The
change-over leads to a modification of the dependent rated figures by a square root
of three.
Attention! The rated data of the motor are to be entered according to the specifi-
cations on the rating plate for the motor connection type used (star or
delta connection).
If the data entered deviate from the rating plate, the parameters will
not be identified correctly. Parameterize the rated data according to
the rating plate of the motor for the wiring of the motor winding. Con-
sider the increased rated current of the connected three-phase motor.
