SAMI STAR變頻器具有REMOTE和LOCAL兩種操作方式。LOCAL操作方式下,通過LOCAL START/STOP開關(guān)啟停變頻器,通過f REF LOCAL INPUT0?輸入端口的電位開關(guān)人工調(diào)節(jié)變頻器工作頻率;通過LOCAL/REMOTE輸入點可以將變頻器切換到REMOTE操作方式下,在REMOTE方式下,通過REMOTE START/STOP輸入點進(jìn)行PLC遠(yuǎn)程啟停變頻器,通過f REF REMOTE INPUT0端口輸入頻率控制信號(百分比)控制變頻器工作頻率。根據(jù)供水量情況,我們把變頻器的工作頻率上限設(shè)定為水泵基頻,即頻率變化范圍控制在0~50Hz,在此范圍內(nèi)水泵運行頻率和定子相壓成正比(及與變頻器輸入頻率成正比),這使得變頻器輸入、水泵運行頻率和泵的輸出壓力成較好的線形關(guān)系,可得到較好的控制效果。SAMI STAR變頻器對用戶開放的I/0接口位于TERMINAL BLOCK CARD上,主要使用的有:X11-1(REMOTE START/STOP);X11-4(LOCAL/REMOTE);X11-13/14(f REF REMOTE INPUT0、4~20mA信號輸入);X11-15/16(輸出4~20mA變頻器運行頻率信號);X11-17/18(輸出4~20mA變頻泵運行電流信號)。變頻器由PLC遠(yuǎn)程控制時,啟動是由PLC向X11-4輸出信號,使變頻器切換到外部設(shè)備控制方式(REMOTE方式),再向X11-1輸出信號,啟動變頻器。在恒壓調(diào)節(jié)時,PLC處理器把檢測到的壓力信號作為反饋值,與PID運算的壓力設(shè)定值(由調(diào)度人員根據(jù)情況在REView上設(shè)定)進(jìn)行比較,再經(jīng)過PID運算得到調(diào)節(jié)后的修正值,通過模擬量輸出模板(1771-OFE)輸出到X11-13/14,作為REMOTE方式下變頻器的頻率控制信號,由于該信號是相對變頻器工作頻率上限的百分比,所以變頻器將輸入信號進(jìn)行內(nèi)部運算后轉(zhuǎn)為真實工作頻率。
