TheOverld availableparameterallowstounderstandifthedriveisreadytosupplyanoverloadcurrent.Ifthe
currentexceedsthevaluedenedbytheBase currentparameter,thetimesetbytheOverload time parameter
startstorun.Oncethistimehasexpired,thecurrentislimitedagaintotheBasecurrent.Thistakesplaceirrespec-
