In the second step, the converter asks for motor nameplate data. After selecting the power, the
nearest motor macro is applied, which preconfigures some system parameters.
When changing power, motor voltage or power factor, the system automatically recalculates the
nominal motor current to estimated value from the power equation. This automatic preset is
suitable for estimating the nominal current in the case where it is not available, e.g. the motor is
physically inaccessible or rewound and nameplate data do not match. After you manually change
the nominal current value, this value will not be recalculated anymore.
Motor overloading [27]
This parameter is used to preset the motor temperature model. When selecting the "Self-cooling",
converter uses thermal model considering its own cooling system, where the cooling effect
increases with speed. In case of using "Forced cooling" thermal model considers the forced
cooling, the effect is constant. The option "Not evaluated" is recommended where the thermal
model should not be evaluated, e.g. when the motor is well cooled or there is another thermal
protection. Setting the External Thermal Protection is out of scope of the wizard, it can be set up
later.
Sine filter [237]
Is there a sine filter connected between the converter and the motor?
7.1.4 Application macros
UNIFREM offers 5 application macros. They are used to preset some of the essential parameters
required for the application. Complete list of these parameters can be found in Table 1 below. The
preset value does not need to be suitable for all variants of the application, however it is very
simple to change it as needed.
