Description:
Adjust them according to the motor nameplate data. If these pieces of information are not available, keep the
default value.
The view of parameters P0433, P0434, P0442 and P0443 will depend on the value set in P0430.
NOTE!
The use of the default value causes:
1. It increases the output current, because the motor in those conditions does not produce the
2. It prevents the motor operation in the field-weakening region.

Note: ke is the generated voltage constant. It is a characteristic of the motor, which determines the voltage generated
as a function of the motor speed. The used engineering unit is V/krpm (Volts/1000 rpm).
