CHV190开环矢量控制在固定式门座起重机上的应用

The Appliation of CHV190 Open-Loop Vector Control To Fixed Protal Crane

本文讲述了CHV190在固定式门座机开环矢量控制改造的实例，实现了无轴编码作位置反馈时，门座式起重机变频改造中的矢量控制。使老式起重设备具备了精度控制与节能运行。

INVT CHV190 series frequency converter could also realize smooth and steady control for crane motor by open-loop vector control , make sure no downwards sliding before starting ,this describes a successful using of open-loop vector control in fixed portal crane alteration projects
