Product Description Product FunctionsThe primary function of a large frequency converter in a wire saw is to achieve stable, efficient, and intelligent control of the diamond wire by precisely controlling the speed and torque of the drive motor.Let's break down its specific functions in detail:1. Core Function: Smooth Speed Regulation and Precise ControlStepless Speed Variable: The frequency converter smoothly adjusts the power frequency supplied to the motor, enabling stepless speed regulation. This allows the operator to precisely set and adjust the wire speed in real time based on factors such as the hardness of the stone, the size of the cut surface, and cooling conditions, achieving optimal cutting efficiency and minimizing tool wear.Maintaining a Constant Linear Speed: During the cutting process, the diameter of the drive wheel changes as the cutting depth increases. The frequency converter adjusts the speed to maintain a constant linear speed of the diamond wire, ensuring a smooth and consistent cut surface.2. Key Function: Soft Start/Soft StopEliminating Starting Shock: Wire saw motors have high power. Starting them directly can generate a significant current surge (typically 5-7 times the rated current) and mechanical shock, which can easily damage the motor, drive system, and wire rope. The VFD enables slow acceleration (soft start), limiting the starting current to less than 1.5 times the rated current, allowing the machine to smoothly reach the set speed, significantly protecting both the machine and the wire rope.Smooth Stop: Similarly, when stopping, the VFD controls the motor to slowly decelerate (soft stop), preventing the wire rope from loosening, swaying, or even breaking due to sudden stops, thereby improving safety and equipment life.3. Core Protection FunctionsOverload Protection: When cutting through particularly hard rock or when a wire rope jam occurs, the load can increase dramatically. The VFD monitors the motor current and torque in real time. If the set values are exceeded, it will immediately issue an alarm or automatically reduce the speed/stop to protect the motor from burning out.Overcurrent, Overvoltage, and Undervoltage Protection: Grid voltage fluctuations and abnormal currents are monitored and protected against.Phase loss protection: Prevents motor damage due to a power phase loss.Overheat protection: Monitors the motor's temperature and that of the motor to prevent overheating.4. Energy saving and efficiency improvementOn-demand power supply: With traditional control methods, the motor may always run at maximum speed, wasting significant energy. The VFD automatically adjusts the motor's output power and speed based on the actual cutting load, providing "just-in-time" power. This eliminates energy waste during no-load and light-load conditions, resulting in significant energy savings, typically reaching 20%-40%.5. Improved cutting quality and automationStable tension control: On high-end wire saws, the VFD can work with a tension sensor to form a closed-loop control loop, ensuring constant tension on the wire rope during cutting. This is key to ensuring a vertical and flat cut surface and preventing deviation.Automation integration: The VFD is a crucial component of automated control systems. It can be connected to the host computer (PLC or industrial computer) through a communication interface (such as Modbus, Profibus, etc.), receive remote commands, upload operating data (such as current, speed, fault code, etc.), and realize remote monitoring, automatic cutting and intelligent management.
