Setting Parameters01/02 AWB8230-1413GBTripping characteristic with normal overload protectionWith normal overload protection (PNU b013 = 01), the trippingcurrent is reduced, for example, by 90 % at 2.5 Hz (a fig. 137).Accordingly, the tripping characteristic is offset to smaller currentvalues (a fig. 140).The tripping curve then has the following characteristic,represented by the frequency set under PNU b018 (a fig. 142).t[s]J[s]60600.50.50 B018: 116 % 120 % 150 %I0 22.9 A104 %29.7 A135 %39.6 A180 %1Figure 142: Tripping characteristic for adjustable overload protectionusing PNU b018Figure 140: Tripping characteristic for constant overload protection at2.5 Hz <strong>and</strong> I e =22ATripping characteristic at adjustable overload protectionHere, you can freely select the tripping characteristic(PNU b013 = 02) by entering the appropriate currency <strong>and</strong>frequency coordinates under PNU b015 to b020 (a fig. 138).These must be within the limits shown (a fig. 141).I[%]10080a0 5400f [Hz]Figure 141: Setting range for the adjustable overload protectiona Setting rangePNU Name Adjustable in RUN mode Value Function WENormalExtendedb012b212Tripping currentfor electronicmotor protectiondevice– j 0.2 to 1.2 xI 1) eSetting range of the tripping current as a multiple of thefrequency inverter rated current, i.e. the range is given inamperes (A).I e1)b013b213Characteristic forelectronic motorprotection device– j The electronic thermal protection of the motor in the low speed range can beincreased to improve thermal monitoring of the motor at low frequencies.00 Enhanced motor protection0101 Normal overload protection02 Adjustable under b015 to b020136
