　　新科瑞變頻器在在砂光機中的應用

　　控制原理：

　　砂光(guang)機(ji)(ji)主(zhu)要(yao)用膠合(he)板的加工以達到厚(hou)度(du)與(yu)光(guang)滑度(du)要(yao)求，傳動(dong)部分主(zhu)要(yao)由砂帶(dai)電(dian)(dian)機(ji)(ji)與(yu)輸送電(dian)(dian)機(ji)(ji)組成(cheng)，其中(zhong)(zhong)傳動(dong)電(dian)(dian)機(ji)(ji)通過變頻(pin)器控制(zhi)，系統由觸摸屏、PLC和(he)變頻(pin)器組成(cheng)，傳動(dong)速(su)(su)度(du)和(he)啟動(dong)命令均在觸摸屏中(zhong)(zhong)設(she)定(ding)，變頻(pin)器調速(su)(su)信號(hao)由PLC根據要(yao)求輸出0~10V模擬信號(hao)，從而控制(zhi)輸送帶(dai)電(dian)(dian)機(ji)(ji)轉速(su)(su)。
