7.5kw CNC servo motor controller variable frequency changer for CNC machine tool
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.
|Input||Rated frequency and voltage|
Three-phase: 380~440V, 50/60Hz;
|Operating range of voltage and frequency||Voltage: ±20%; frequency: ±5%|
|Over-load capacity||1min at 150% of the rated current and 1s at 200% of the rated current|
|Main control properties||Control mode||Vector control|
|Range of speed regulation||1:100|
|Torque characteristics||High torque output, starting torque can reach 150% at 1Hz.|
|Frequency accuracy||Digital setting: ±0.01%; analog setting: ±0.2%|
|Frequency resolution||Digital setting: 0.01Hz; analog setting: 0.1% of the max. frequency|
|Start modes||3 modes: start from start frequency, start after brake and start after rotating speed tracking|
|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 modes||3 modes: decelerated stop, decelerated stop+DC braking and free stop|
Start frequency of braking: 0~60.00Hz, or determined by external input terminals.
|Dynamic brake||Adjustable max.braking torque.|
|Jog||Range of jog frequency: 0.00~upper limiting frequency; jog acceleration/deceleration time: 0.0~6553.5s; jog interval can be set.|
|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.|
