Toshiba VFS11-4015PL-WN Variable Frequency Drive

The Toshiba VFS11-4015PL-WN is a 1.5 kW (2 HP) transistor inverter (Variable Frequency Drive) from the TOSVERT VF-S11 series, designed to control the speed and torque of three-phase AC motors in industrial automation. It supports 3-phase 380–500 VAC input and 3-phase 380–500 VAC output, with an adjustable output frequency range of 0.1–400 Hz and a rated output current of 4.1 A, making it suitable for a range of industrial drive tasks. Control methods include Sensorless Vector Control or V/f control, and communications cover RS-485/RS-422 with Modbus RTU. It provides two analog inputs (0–10 V, 0/4–20 mA) and three transistor outputs plus two relay outputs for basic external I/O, with an integrated LED keypad display for on-panel configuration. The unit is intended for wall mounting and includes protection features such as overcurrent, overload, short circuit, motor ground fault, overtemperature, and undervoltage. Common replacements include Toshiba VFS11-4015PL-WP, VFS15-4015PL-WN, and VFNC3-4015P. This drive is commonly used in industrial conveyor systems, centrifugal pumps, HVAC equipment, air compressors, packaging machines, food processing equipment, textile machinery, machine tools, material handling systems, and other manufacturing automation applications requiring precise variable speed control of three-phase induction motors. Maintenance teams, OEM machine builders, and system integrators rely on this inverter for drive replacement, control system retrofits, and restoration of motor control performance.
