  1. And the inverter becomes smarter. during the designing, the pulse - processing ciucuit is preset which processes the feedback pulse from photoelectric encoder for close - looping the system in future. by using the circuit and quadrature mode of timer 1 in 80c196mc, incremental encoder can be embedded into the velocity regulation system more easily and the domain the inverter can be used in is enlarged too

    在系統設計過程中,考慮到了變頻調速器進一步改進為閉環系統的需要,在電路中預設了光電碼盤反饋脈沖的處理電路,通過這個電路的處理,並利用80c196mc中定時計數器1的90相移計數工作方式,可大大簡化使用增量式光電碼盤時脈沖處理的復雜度,這也擴大了本文中變頻調速器的應用范圍。
