S/NOSOFT STARTER VARIABLE FREQUENCY DRIVE
01Ni maalumu kwa ajiri ya kuanzisha motor baada ya hapo inatumika kama contakta ya kawaida Ni maalumu kwa ajiri ya kuanzisha na kupingilia mwendo sawa na mahitaji
02Hutumia sheria ya kuathiri Voltage ili kudhibiti mtiririko (Over current ) kipindi motor inaanza kuwashwaHuathiri umara (Frequency ) ili kupata mwendo tunaotaka
03Haiendelei na kupokea wala kutoa taarifa za hali na mwenendo wa motor badala yake husubiri maelekezo ya kuzima ama kuwaka kutoka control room / stations Huendelea kutoa na kupokea maelekezo juu mwendo wake (Controls input and output signals (4 -20mA)
