摘要
本文介绍了基于LabVIEW的交流伺服电机转速测试方法。提出了通过工控机控制NI数据采集卡PCI-6251的AO输出信号,通过驱动放大单元后驱动交流伺服电机;同时使用数据采集卡PCI-6251的AI测量红外对管脉冲,从而达到测量电机转速。最后给出了部分程序。
This paper introduces a rotation speed measurement method of AC servo machine based on LabVIEW. It provides that .40 output signal of NI data acquisition card PCI-6251 should be controlled through industrial completer, and AC servomotor is driven after through driving magnified units. The pulse of infrared emitting diode and photodiode is measured by AI of PCI-6251 data acquisition card, the rotate speed is gotten and some programs are given.
