The single phase input and three phase output 220V SN200MN series VFD is a general purpose high performance with low speed and high torque output. It has good dynamic characteristics, powerful functions but smaller size due to its compacted design. It based on the software platform of SN200G series frequencyconverter . Besides, it can be widely used in a variety of complex occasions with a high performance.
1)Various voltage levels: it supports three voltage levels- singl phase 220V, three phase 220V, and three phase 380V
2) Rich control methods: in addition to the speed sensor vector control, sensorless vector control, V/F control, it also supports V/F separation control
3) Optional field bus: it supports two kinds of bus-Modbus-RTU and CANLINK
4) Rich types of encoders: it supports differential encoder, open collector encoder, rotary transformer, etc.
5)Brand new sensorless vector control algorithm
The new SVC(sensorless vector control) brings better low-speed stability, stronger low-frequency load capacity, and the support for SVC torque control
6)Strong background software: the background software can achieve the frequency converter parameters of the upload download, real-time oscilloscope and other functions.
Advantages of SN200MN Series frequency converter
1. Restore user parameters: This function supports the customer to save or restore the parameters of its own settings.
2. Display of customized parameters: Functional parameters to be displayed for user customization
3. Display of revised parameters: The user can view the modified function parameters
4. Fault processing options: According to the needs, the user can determine the operating mode of the frequency converter after a specific fault occurs: free stop, deceleration, stop, and continue to run. It is also possible to choose the frequency of the continuing operation.
5. PID parameter switching: There are two sets of PID parameters, which can be switched by terminal switch or according to the deviation.
6. PID feedback on loss detection: Setting the PID feedback on loss detection value to realize the protection of the PID during the running.
7. DIDO positive and negative logic: User-set positive and negative logic of DIDO.
8. DIDO response delay: The user sets the DIDO response delay time.
9. Run timing: Support timing maximum 6500 minutes for running.
10. Wireless remote control: The extended wireless module is used to set and control the remote parameters.
The VFD's panel can be removable
