FST-610 Series High-Performance Vector Inverter (250kW-355kW)

The Anyhz FST-610 is a high-performance universal vector inverter engineered to replace virtually any general-purpose VFD on the market. With its advanced sensorless vector control (SVC) technology, the FST-610 delivers 180% starting torque at 0.5Hz and a 1:100 speed regulation range—performance that matches or exceeds most mainstream drives at a fraction of the cost.

The 250kW-355kW metal cabinet variant is designed for heavy-duty industrial applications where reliability, torque performance, and overload capacity are critical. Built with a rugged metal enclosure and enhanced thermal management, this range powers the most demanding equipment in mining, cement, metallurgy, water treatment, and heavy manufacturing.

• Three Control Modes in One Drive: V/F control, sensorless vector control (SVC), and torque control—handle any heavy-load profile

• 9 Frequency Setting Methods: Digital, analog, pulse, serial communication, multi-speed, simple PLC, PID, and more—compatible with any control system

• Built-in Process PID: Closed-loop control for pressure, temperature, flow rate—no external controller needed

• Rich Parameter Functions: Pulse frequency setting, multi-speed & simple PLC, swing frequency control, momentary power loss ride-through, automatic voltage regulation (AVR), DC braking, inching operation, counting control, and more

• G/P Type Dual Load Rating: G-type for heavy-duty (150% overload/60s, 180%/10s), P-type for fans/pumps (120% overload/60s, 150%/10s)

• Universal Voltage Compatibility: Three-phase 380V standard

• Modbus RTU Communication: Standard RS485 interface for easy integration into SCADA/DCS systems

• Rugged Metal Cabinet Design: Enhanced heat dissipation, IP protection, and structural integrity for harsh industrial environments

Built-in PID controller maintains constant pressure or airflow across wide demand variations. AVR function stabilizes output during grid fluctuations common in industrial plants. Energy-saving mode reduces power consumption by 20-40% for centrifugal loads. Common DC bus option enables energy recovery in multi-fan systems.

Key benefits: Constant pressure/flow, soft start eliminates mechanical shock, sleep/wake for variable demand, energy recovery

Recommended models: FST-610-250G/280PT4 (250kW), FST-610-280G/315PT4 (280kW), FST-610-315G/355PT4 (315kW), FST-610-355G/400PT4 (355kW)

High starting torque handles water hammer and high-static-head starts. Built-in PID with sleep/wake function optimizes energy in municipal and industrial pumping stations. Momentary power loss ride-through prevents nuisance tripping during grid disturbances. Multi-pump control logic via simple PLC eliminates external controllers.

Key benefits: Water hammer protection, constant pressure/flow, multi-pump sequencing, grid disturbance immunity

Recommended models: FST-610-250G/280PT4 (250kW), FST-610-280G/315PT4 (280kW), FST-610-315G/355PT4 (315kW), FST-610-355G/400PT4 (355kW)

180% starting torque at 0.5Hz breaks through jammed loads and handles high-inertia startups. Robust overload capacity (150%/60s, 180%/10s) withstands surge loads from ore variability. Metal cabinet construction with enhanced cooling survives dusty, vibrating environments. Torque control mode prevents mechanical damage during blockage events.

Key benefits: Jammed-load breakthrough, surge load tolerance, vibration-resistant cabinet, torque-limiting protection

Recommended models: FST-610-250G/280PT4 (250kW), FST-610-280G/315PT4 (280kW), FST-610-315G/355PT4 (315kW), FST-610-355G/400PT4 (355kW)

Precise speed control ensures optimal grinding efficiency and product consistency. Sensorless vector control eliminates encoder cost and maintenance in dusty environments. High overload capacity handles periodic peak loads from mill charge variations. Automatic voltage regulation maintains output during weak grid conditions common in remote plants.

Key benefits: Grinding efficiency optimization, encoder-free precision, peak load tolerance, weak-grid stability

Recommended models: FST-610-250GT4 (250kW), FST-610-280GT4 (280kW), FST-610-315GT4 (315kW), FST-610-355GT4 (355kW)

Torque control mode maintains consistent mixing intensity across varying material viscosities. High starting torque overcomes initial material resistance. DC braking ensures rapid, controlled stopping for batch processes. Simple PLC function automates multi-stage mixing profiles without external controllers.

Key benefits: Consistent mixing torque, viscosity adaptation, controlled stopping, automated batch profiles

Recommended models: FST-610-250G/280PT4 (250kW), FST-610-280G/315PT4 (280kW), FST-610-315G/355PT4 (315kW), FST-610-355G/400PT4 (355kW)

Bottom line: The FST-610 delivers high-performance vector control features found in premium drives costing 30-50% more, with universal compatibility that allows it to directly replace virtually any heavy-duty VFD on the market—while offering superior functionality, robust construction, and proven stability at a competitive price point.
