I have noticed that Sinamics S120 booksize has a different procedure of G120 for forming DC link capacitor. In Sinamics S120 booksize is necessary to supply voltage to U2, V2, W2, (inverter output, with series lamps/resistor) as attached picture. For G120, power is supplied to the main input (L1, L2, L3, also with series lamps/resistor). Why is that difference? For booksize module, if the control voltage (gate) of output IGBT is completely switched off during the forming procedure, how the 3-phase-supply is rectified to generate DC-current and charging the capacitor? Finally, in the attached picture, does the procedure reform both Line Module and Motor module or only Line Module? Best Regards. Silvio Morais
