510 Series 3.7-5.5KW Frequency Converter

XH510 series 3.7KW & 5.5KW high-torque frequency converters are specially tuned for heavy-cutting machine tools, large stone processing and textile spinning heavy loads, upgrading the heat dissipation structure compared with low-power models to sustain long-hour heavy-load operation. This power segment supports high-current output to drive large spindle motors, with optimized slip compensation and torque compensation algorithms to guarantee stable low-speed cutting force for metal and stone processing equipment.
All units retain standard Modbus communication protocol and synchronous motor compatibility; customers for stone sawing machines can customize built-in braking resistors to handle fast deceleration of heavy rotary blades. The enlarged cabinet body enhances heat dissipation, lowering overheat protection trigger frequency under 24-hour non-stop production.

Core Performance Highlights

Torque compensation & slip compensation built-in, steady 150% low-speed torque to avoid cutting vibration during metal engraving and stone slab processing

Enhanced over-current stall limit and fast current limiting functions, automatically suppress surge current when cutting resistance suddenly rises

Multiple V/F curve modes (linear, multi-point, full/half V/F separation), freely matched to different spindle motor characteristic curves

Wider ambient temperature adaptability: continuous full-load work at -10℃~40℃, derating operation available up to 50℃ for poorly ventilated processing workshops
