Detailed Description – Toshiba VFS15 Inverter Series

1. Series Overview – High-Performance Micro Drives

The Toshiba VFS15 series (also known as TOSVERT VF-S15) is a compact, high-performance adjustable speed drive designed for a wide range of variable and constant torque applications . Engineered for reliability in demanding environments, the S15 offers heavy-duty overload ratings (150% for 60 seconds, 200% for 0.5 seconds) and operates at ambient temperatures up to 60°C with derating . The series covers multiple voltage classes—200V, 400V, and 600V—making it suitable for diverse global power systems .

Key Family Features:

• ✓ Broad power range – 0.2 kW to 22 kW across 200V, 400V, and 600V classes 

• ✓ Heavy-duty overload rating – 150% for 60 seconds, 200% for 0.5 seconds 

• ✓ High ambient temperature capability – up to 60°C (with derating) 

• ✓ Vector control & V/f modes – Sinusoidal PWM control, automatic torque boost, energy-saving control for fan/pump applications 

• ✓ Integrated communications – Modbus RTU and RS485 serial port standard 

• ✓ Programmable I/O – 6 digital inputs, 3 programmable outputs (relay + open collector), 3 analog inputs, 1 analog output 

• ✓ Compact footprint – One of the smallest micro drives available, ideal for space-constrained panels 

• ✓ Permanent magnet motor compatible – Operates with PM motors for enhanced energy savings 

• ✓ IP20 enclosure – Wall mount design with forced air cooling 

• ✓ CE & UL certified – Meets global safety and EMC standards 

2. 200V Class Series – Single & Three-Phase Input

The VFS15-2 series covers low-voltage applications with both single-phase (S variant) and three-phase input options.

Key Specifications:

3. 400V Class Series – Standard Industrial Voltage

The VFS15-4 series is the most widely used voltage class for industrial applications, supporting 3-phase 380-500V input.

Key Specifications:

Note: Models with “PL1” variant (e.g., VFS15-4015PL1-W1) indicate a second-generation version with identical power ratings but updated hardware. For example, VFS15-4015PL1-W1 delivers 1.5kW output, 4.1A input current, and 380-500V input .

Key Functions:

• ✓ 15 preset speeds – Selectable via digital inputs 

• ✓ Built-in PID regulator – For precise process control 

• ✓ Modbus RTU – Standard communication protocol 

• ✓ 3 digital + 2 relay outputs – Programmable for various status signals 

• ✓ Multiple analog inputs – 0-10V, 4-20mA, or external potentiometer 

• ✓ Protection – Short circuit, overload, earth fault, over-temperature 

4. 600V Class Series – Heavy Industrial Applications

The VFS15-6 series is designed for 600V industrial systems, offering robust performance in demanding environments such as mining, cranes, and crushers .

Key Specifications:

Environmental Specifications:

• ✓ Ambient temperature: -10°C to +60°C (with derating above 40°C) 

• ✓ Altitude: Up to 1000m without derating 

• ✓ Humidity: 95% non-condensing 

• ✓ Protection: IP20 

• ✓ Cooling: Forced air-cooled 

• ✓ PWM carrier: Adjustable 2-16kHz (default 12kHz for ≤15kW)
