B0H STARTUP / Drv & Mot config / Mot ovld
B0H.00 Mot service fact N/A RW 1 0.5/1.5 FK V-F-S-B Easy 1611
Service factor. Some motors have a motor continuous current (Ic) higher than the rated
current (In). The service factor makes reference to the Ic/In ratio.
B0H.01 Motor OL factor N/A RW 2 1.2/5 FK V-F-S-B Easy 1610
Allowed motor overload factor referring to the Motor rated current * Service factor.
B0H.02 Motor OL time [sec] RW 30 10/Calc FK V-F-S-B Easy 1650
Allowed overload time with overload level equal to B0H.01 - Motor OL factor.
The integrator state is given by:
Mot OL accum % it gives the percentage state of the Rms current integration. 100 % = I2t
alarm level. It is available as a digital signal in the Pick List selections.
Mot OL trip It states that the trip condition of I2t has been reached. Possible or non-
possible overload.
The intervention time depends on the value of the motor current as follows:
(Motor Rated current * Service factor * Motor OL factor )^2* Motor OL time
Overload time = ————————————————————————————————
