Product Details

7.5kw CNC spindle inverter stepper motor driver for CNC lathe machine tool



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




1. Small size


2. The built-in PID control and sleep/wake function


3. Simple positioning function, the positioning error is less than 10 degrees


4. 7 speed programming operation


5. Instantaneous power restart function to ensure that the system run continuously


6. Built-in standard MODBUS communication interface


7. The output frequency range: 0.1 Hz ~ 400.00 Hz


8. Powerful automatic torque and manual adjustment, V/F curve of motor starting torque at low speed

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.

InputRated frequency and voltage

Three-phase: 380~440V, 50/60Hz;
three-phase/single-phase: 220~240V, 50/60Hz

 Operating range of voltage and frequencyVoltage: ±20%; frequency: ±5%
OutputVoltage0~input voltage
 Over-load capacity1min at 150% of the rated current and 1s at 200% of the rated current
Main control propertiesControl modeVector control
 Range of speed regulation1:100
 Torque characteristicsHigh torque output, starting torque can reach 150% at 1Hz.
 Frequency accuracyDigital setting: ±0.01%; analog setting: ±0.2%
 Frequency resolutionDigital setting: 0.01Hz; analog setting: 0.1% of the max. frequency
 Start modes3 modes: start from start frequency, start after brake and start after rotating speed tracking

deceleration modes

3 modes: straight line mode, settable S-curve mode (independently adjustable proportions of start and end sections of S-curve) and automatic acceleration and deceleration mode
 Stop modes3 modes: decelerated stop, decelerated stop+DC braking and free stop
 DC braking

Start frequency of braking: 0~60.00Hz, or determined by external input terminals.
Braking time: 0.0~60.0s, or determined by external input terminals.
Braking current: 0.0~100.0% of the rated current of frequency converters

 Dynamic brakeAdjustable max.braking torque.
 JogRange of jog frequency: 0.00~upper limiting frequency; jog acceleration/deceleration time: 0.0~6553.5s; jog interval can be set.
 Automatic voltage regulationWhen input power grid voltage fluctuates, stability of output voltage can be kept automatically.
 Fast current limitFast 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 regulationCarrier frequency can be automatically regulated to optimize system state in accordance with load characteristics.
