传动使用现代IGBT 逆变技术。无论输出频率是多少，传动都会输出电压相当于中间直流回路电压的脉冲，且上升时间非常短。根据波的传导与反射理论，电机端子产生比中间直流回路电压高很多的尖峰电压，甚至达到两倍直流电压。这个具有很大du/dt 值的尖峰电压会对电机和电机电缆绝缘带来额外的压力。这将会缩短电机的寿命。
ABB 的 可选件du/dt 滤波器可以保护电机及电缆的绝缘系统。

Information) system pioneered and led by ABB in technology.
information technology) new trends.
The system is divided into two levels: operation management level and process control level. At the operation management level, not only the traditional control system monitoring operation function is realized
function (operation and display, printing, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems.
can. The process control stage realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control.
Control, sequence control and batch intermittent control functions.
The internal communication of the process control station (between the controller and various intelligent devices such as I/0 or field instruments) adopts the international standard field controller.
Wire. The field controller supports various field buses such as Profibus. Profibus is the most widely used open field bus in the world.
Line international standard, divided into FMS, DP and PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard),
Users can choose the communication transmission medium (ordinary cable or optical fiber) and network topology according to the actual situation of the application.
The popular PC and MS_ Windows 2000 have been widely used in various fields all over the world, becoming the de facto standard computer platform.
tower. The operating station 0S, the engineering station ES and the data gateway GS of the Industrial” system use this platform to ensure the system’s
Versatility, openness and ease of use, and bring great convenience
