Kinda variable freqyency drive applied in CNC machine

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

14	F1-11	0	0.5	DC braking start frequency while stopping
15	F1-12	0	0s	DC braking delay time while stopping
16	F1-13	0%	100%	DC braking current while stopping
17	F1-14	0s	1s	DC braking time while stopping

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.
