7.5kw CNC servo motor three phase VFD CNC servo converter for CNC
INVOEE,China top one brand of CNC spindle VFD.We focus on CNC lathe
spindle VFD inverter research and prouction with rich experience,
high precision,easy operation and maintenance.
VC610,VC660,VC680,VC690 gradually upgraded function are as follows:
VC610 :1.stable rotating speed. 2.Stepless speed control. 3.Low speed
large torque.4.Quick start and stop.
VC660 VFD has the sames function with VC610,at the same time,it adds
Communication port, S curve, external keyboard.
VC680 VFD adds spindle positioning servo function.
VC690 VFD adds:1.Spindle positioning servo function,2.Rigid tapping and
thread cutting ,3. Position interpolation.
VFD Main Characters:
1. Suits the occasions which demands: Quick start quick stop;
Precise positioning; High speed running.
2. Easy parameter bugging;
3. Turning to your desired special model by one key setting only
4. Parameter copy function, making the operation quite easy

|Automatic voltage regulation||When input power grid voltage fluctuates, stability of output
voltage can be kept automatically.|
|Fast current limit||Fast current restraining ability prevents frequent over-current
trips and realize the characteristics of excavator (output torque
is kept for locked-rotor of motors).|
|Automatic carrier regulation||Carrier frequency can be automatically regulated to optimize system
state in accordance with load characteristics.|
