4KW 380V VSD Variable Speed Drive is applied to CNC machine tools
1, Load feature
CNC machine is a mechanical-electrical integrated system include mechanic, electric, hydraulic, pneumatic, microelectronics and information technology, it has the features of high accuracy, highly automated and highly flexible.
2, Requests for inverters (VFD)
(1) It can work normally at 300RPM speed, has good stability, high control accuracy, fast response speed and high output torque at
low speed.
(2) It should have external forward / reverse control signal and analog input signal.
3, Instruction for commissioning

4, Notices
(1) Under the SVC control mode, it must perform the auto tunning firstly, then set the other parameters.
(2) Please pay attention to ACC/DEC time setting and also the braking resistor’s selection.
(3) The installation environment should be safe, to avoid the iron dust and other items to enter into inverter.
