Its purpose is to estimatethe motor Local Control Panel (LCP102)InitialisingIf initialising is carried out (14-22 Operation Mode), theprogrammable parameters of the frequency converterreturn to their default Duty CycleAn intermittent duty rating refers to a sequence of dutycycles. Each cycle consists of an on-load and an off-loadperiod. The operation can be either periodic duty or none-periodic Local Control Panel makes up a complete interface forcontrol and programming of the frequency converter. TheLCP is detachable and can be installed up to 3 metresfrom the frequency converter, in a front panel bymeans of the installation kit LCP is available in 2 versions:-Numerical LCP101 (NLCP)-Graphical LCP102 (GLCP)lsbLeast significant for Mille Circular Mil, an American measuring unit forcable cross-section.
