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
name 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 corre-
sponding 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 torque
if the motor winding can be switched over from star to delta connection. The change-
over results in a change of the dependent parameters by a factor of square root of 3.
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 specifications for the motor winding connection indi-
cated on the rating plate. Take the higher rated current of the con-
nected asynchronous motor into account.
