The FST-580 mini VFD drive achieves its compact form factor through high-density PCB design and advanced thermal management. At just 72mm wide for the 0.75-2.2kW range, it is approximately 40% smaller than conventional drives of equivalent power—making it ideal for OEM machinery, crowded MCCs, and wall-mounted residential panels.

Single-phase 220V input models (FST-580-xxxS2) output three-phase 220V—suitable for 220V three-phase motors. For 380V three-phase motors, you must use the FST-580-xxxT4 models with three-phase 380V input. The S2 series cannot step up voltage to 380V.

Yes. Unlike standard compact drives that only support induction motors, the FST-580 mini vector inverter includes dedicated parameters for PMSM (b1-16 ~ b1-20, b2-26 ~ b2-44). It supports both loaded and no-load tuning for synchronous motors, making it future-proof for high-efficiency motor upgrades.

Navigate to parameter b0-29 (Application Macro) and set it to 1 (0-10V pressure) or 2 (4-20mA pressure). The drive automatically configures PID parameters, sleep/wake thresholds, and protection alarms. Fine-tune pressure settings via the C5 group parameters (C5-00 sensor range, C5-01 target pressure, C5-02/C5-03 sleep/wake levels).

Standard mode: 0-320.00Hz. For high-speed spindles, set b0-22 = 1 to enable 0-3200.0Hz output. Note that when b0-22=1, acceleration/deceleration time units and display resolution adjust accordingly.

No. The FST-580 operates in sensorless vector control (SVC) mode without encoder feedback. This saves cost and eliminates encoder maintenance. For applications requiring ±0.02% speed accuracy, consider our FST-860 closed-loop vector series.

The drive includes 20+ protection types: overcurrent (acceleration/deceleration/constant speed), overvoltage, undervoltage (Err09), motor overload (Err11), inverter overload (Err10), input/output phase loss (Err12/Err13), module overheat (Err14), external fault (Err15), motor short-to-ground (Err23), and user-defined faults (Err27/Err28).

Yes. When b0-02 = 2 (communication command channel), the drive accepts Modbus-RTU commands for start/stop, frequency setting, and parameter modification. The L/R indicator flashes to confirm communication control mode.
