Selection of SN200MN frequency inverter
Function Features of SN200MN VFD:
1. Virtual IO function
5 groups of virtual DIDO can be set. The status of terminal DI can be given directly by functional code or bound to corresponding Virtual DO function.
2. Multi motor switching
With 4 sets of motor parameters, the switching control among 4 motors or between synchronous motor asynchronous motor can be realized.
3. Fast current limiting function
Fast current limiting function can avoid frequent overcurrent alarm of the VFD. When the current exceeds the current protection point, the fast current limiting function can quickly limit the current to the current protection point, so as to protect the device and avoid overcurrent alarm caused by sudden load or interference.
4. Nonstop at jnstant outage
The function means that the VFD will not stop at the time of power outage. In case of instantaneous power failure or sudden voltage drop, the VFD reduces output speed and compensates the voltage reduction by feedback energy, so as to maintain the inverter running in a short time.
5. Flexible and practical analog input/output port
Each analog input ( A11～A13) is set respectively for 4 points of the curve, more flexibly in use.
A11~A13 can be corrected by factory before delivery or calibrated by user of the linear curve, and the accuracy after calibration is up to 20mV. AO can be corrected by factory before delivery or calibrated by user of the linear curve, and the accuracy after calibration is up to 20mV.
A11~A13 can be used as a DI.
A13 is an isolated input port, which can be used as a PT00, PT1000 or + 10V input port.
