VFDs play a vital role in the sheet metal engraving and cutting industry. Through precise speed regulation, energy conservation, and motor protection, they improve processing accuracy and efficiency, meeting diverse processing needs. With the continuous development of technology, specialized VFDs will become more intelligent, energy-efficient, and environmentally friendly, bringing greater development opportunities to the sheet metal engraving and cutting industry.
1）Control Requirements
High-precision speed control: The VFD must be able to adjust the speed stably and accurately over a wide speed range, ensuring that the engraving tool runs at a constant speed, guaranteeing engraving accuracy and surface quality.
Low-frequency, high-torque output: When engraving hard materials or creating fine reliefs, the VFD must provide sufficient torque at a low frequency to ensure smooth cutting of the tool and avoid stalling or damage.
Fast acceleration and deceleration: The VFD must have rapid acceleration and deceleration capabilities to accommodate the rapid switching between different speeds during the engraving process, improving production efficiency and processing flexibility.
Steady Speed Operation: During high-speed rotation, the inverter must ensure stable spindle motor operation, reducing speed fluctuations and improving processing accuracy. Adaptability to Different Materials: The VFD must adjust the output frequency and speed based on the material and thickness of the sheet material to ensure optimal processing quality.
Reliability: The VFD must incorporate multiple internal protection mechanisms to prevent damage to the motor and equipment, ensuring a stable and continuous production process.
