Spindle VFD Variable Frequency Drive Engraving Machine Application 1.5KW
With its unique super performance and superior cost performance, the inverter meets the performance requirements of wide range of speed regulation, high speed stability, strong overload capability, large low speed torque, short acceleration and deceleration time, etc. Level speed regulation, according to different engraving objects or engraving process, change the spindle cutting speed in real time. It is widely used in medium and high-end engraving machines that require high and fine engraving process.
