8.1 Motor data
Optimisation of the control loopsOptimisation of motor controlSetting of motor data Motor control selection
The term "motor data" comprises all parameters only depending on the motor and only char-
acterising the electrical behaviour of the machine. Motor data are independent of the applica-
on in which the inverter and the motor are used.
Precondions
When you enter the motor nameplate data, take into account the phase connecon imple-
mented for the motor (star or delta connecon). Only enter the data applying to the connec-
on type selected.
Possible sengs
If a Lenze motor is connected to the inverter, you can simply select the used motor in the
engineering tool from the "motor catalog".
•
For details see chapter "Motor selecon from motor catalogue". ^ 144
Otherwise the motor data has to be set manually (see the following subchapter).
8.1.1 Manual seng of the motor data
If an external motor is connected to the inverter, the motor data must be set manually in the
following parameters according to the manufacturer informaon/motor data sheet.
