今天我们了解一下ebm专用控制器是如何调速风机的？

Hello everyone,welcome to Sherry's fun fan Classroom.

Today we will learn about how does the EBM dedicated controller control the speed of the fan?

FFU被广泛应用于芯片制造，集成电路，生物制药行业的洁净室中。R3G470-AB05-24和R3G470-AA05-24两款EC离心风机以稳定的风量在多个项目中使用，同时配合ebm专用控制器CHW040实现调速。

FFU is widely used in clean rooms of chip manufacturing, integrated circuits, and biopharmaceutical industries. The R3G470-AB05-24 and R3G470-AA05-24 EC centrifugal fans are used in multiple projects with stable airflow, cooperating with the ebmpapst dedicated controller CHW040 to achieve speed regulation.

刚接触的用户可能不太会使用，不用担心，让我们帮您展示！

New users may not be very proficient in wiring,don't worry,let us demonstrate for you!

（实物展示视频）控制器与风机的接头是已经通过子母头匹配好，直接插好即可，

The connectors between the controller and the fan are already matched with plug-and-socket pairs, so they can be directly plugged in.

控制器接通1~220伏 50hz的交流电，控制器开始工作，

Connect the controller to single-phase 220V/50Hz AC power, the controller start working,

单击MODE键，切换至on/off功能。通过上下键选择on，并且set确认后，使风机启动，

Press the MODE button to switch to the on/off function. Use the up and down keys to select 'on,' then confirm with the SET button to start the fan.

单击MODE键，切换至SET功能。通过上下键增加或减少转速值，选定后set确认，使风机加减速运行，并且在显示屏上显示实际转速。

Press the MODE button to switch to the on/off function. Using the up and down keys to increase or decrease the speed value, then confirm with the SET button. This will adjust the fan speed, and the actual speed will be displayed on the screen.

控制器同时支持风机监控功能，当出现报警时，会在显示报警代码同时停机，根据代码可以查询故障原因。

The controller also supports fan monitoring. When an alarm occurs, it displays an error code and shuts down the fan. The error code can be used to identify the cause of the issue.
