【摘要】 针对变频器批量组装完成后对其运行稳定性能测试的要求,设计一种基于S7-200PLC控制的变频器老化测试电气控制系统,提出一种多工位测试多种型号、基于间接寻址的模块化编程方法,结合模块化硬件设计实现变频器的老化测试系统.该测试系统的软件结构性强,可靠性高,硬件运行稳定,易于设备维护更新.实际使用表明其在工业应用中具有较高的实用价值.更多还原

【Abstract】 Aiming at testing performance requirements of the factory massive assembled inverters,an inverter burning system based on S7-200 Programmable Logic Controller supporting multiple stations is carried out. In this control system,the indirect addressing method is applied in program and the modular hardware configuration is adapted to every station.All the features make this system more modularized,more stable,and easier to maintain and upgrade. Actual use of the system shows that it has high practical value in industrial applications.更多还原
