VFD for straightening machine
The configuration of the steel plate fixed size cutting equipment:
Loading trolley, uncoiling machine, board swaging device, six-layer straightening machine, tracking shearing system, conveying and lifting work platform, double-layer pneumatic layout shelf, hydraulic system, electrical control system. The overall system adopts the VFD, PLC, touch screen, rotary encoder and other components to constitute the automatic control system of the production line. Under the premise of giving consideration to both horizontal shearing precision and manufacturing efficiency, through utilizing the high-speed counting function of the PLC and the speed regulating and controlling function of the VFD, so as to control the starting, running, speed reducing, crawling and accurate stopping of the straightening roller and pressing roller effectively, thus realizing the high-efficient and automatic cutting fixed size of the metal plate.
Parameter setting of ATO VFD for straightening machine
|Function code||Name||Set value||Remark|
|P0.01||Frequency setting channel||6||CI analog quantity setting|
|P0.03||Operating command channel||1||Terminal operation|
|P0.17||Acceleration time 1||2||Set according to the field condition|
|P0.18||Deceleration time 1||2|
|P0.06||Maximum output frequency||60|
|P0.19||Upper limiting frequency||60|
