The non-condensing function consists in injecting DC into the motor. DC current brakes the motor and heats the motor
windings, thus avoiding condensation. This function is active only for the IFD control if C221 is other than zero and the
ENABLE function is activated. For the other control algorithms, the non-condensing function is performed by injecting
current during motor fluxing. Parameter C221, expressed as a percentage of the rated current of the controlled motor,
determines the level of direct current injected into the motor.
Parameters used to program this function are the following:
C216 enabling DCB at Start;
C218 setting the duration of DCB at Start;
C220 setting the intensity of the DC braking;
C221 setting the intensity of the holding current (this function is active for the IFD control only).
