Product Overview
When you need reliable motor control for 3-phase induction or permanent magnet AC motors, the FANUC VFAS3-4015PC delivers. This Toshiba AS3 series AC drive combines high-performance control modes with built-in features that reduce installation costs and simplify system integration. With a nominal input and output voltage of 460 VAC and 2 HP with 3-phase input, it handles demanding applications efficiently.
Technical Specifications Breakdown
Power and Performance
The VFAS3-4015PC operates at 460 VAC input and output, drawing 4A (5.6A variable torque rating). This 2 HP drive supports a carrier frequency range of 1-16 kHz and an output frequency range of 0.1-590 Hz. The integrated dynamic braking reduces external component costs, while the built-in DC reactor and EMC filter minimize harmonic distortion and electromagnetic interference.
Control Modes
Choose from V/Hz, FOC (Field-Oriented Control), encoder, or torque mode. This flexibility lets you optimize energy use for different loads. For example, FOC mode improves efficiency in variable-speed applications, lowering electricity costs over time.
Communication and I/O
The drive includes two Ethernet ports (RJ45) supporting EtherNet/IP, Modbus TCP, and a non-secure HTTP webserver, plus one RS-485 port (RJ45) for Modbus RTU Slave. This reduces wiring and commissioning time compared to older serial-only systems. Analog inputs (3 channels, 0-20 mA, 4-20 mA, +/-10 VDC, 11-bit) and outputs (2 channels, 0-20 mA, 4-20 mA, 0-10 VDC, 10-bit) enable precise feedback. Eight discrete inputs (24 VDC, sinking/sourcing) and three relay outputs (250 VAC/30 VDC, 2A) handle control and signaling.
Environmental and Physical
Rated for -15 to 50 deg C, IP20, and UL Type 1 enclosure, the drive mounts on a panel or wall in A1 frame size. The built-in Safe Torque Off (STO) enhances safety without external relays.
Industry Applications
Conveyor Systems
In material handling, the VFAS3-4015PC's V/Hz or FOC mode adjusts speed to match load, reducing mechanical wear and energy consumption. The integrated dynamic braking handles rapid stops, lowering maintenance costs.
Pump and Fan Control
For centrifugal loads, variable torque rating (5.6A) and 0.1-590 Hz output allow precise flow control. The built-in EMC filter simplifies compliance with noise regulations, avoiding costly external filters.
Machine Tool Spindles
Encoder or torque mode provides accurate speed and torque control for machining operations. The 1-16 kHz carrier frequency reduces motor audible noise, improving operator comfort.
Installation and Setup Guidance
Mount the drive on a clean, flat panel or wall using the A1 frame mounting holes. Ensure adequate ventilation for the -15 to 50 deg C ambient range. Connect 3-phase 460 VAC input to the screw terminals. Use shielded Ethernet cables for communication ports. Set control mode via user sequence programming. Install a user-supplied external fuse per local codes. The conduit box simplifies wiring.
Maintenance and Reliability
Periodically inspect the drive for dust accumulation on the heatsink and verify terminal tightness. The integrated EMI filter and DC reactor reduce stress on internal components, extending service life. Operating within the -15 to 50 deg C range prevents thermal derating. The built-in STO function allows safe maintenance without disconnecting power, reducing downtime.
Compatibility and Integration
The VFAS3-4015PC integrates with PLCs and controllers via EtherNet/IP, Modbus TCP, or Modbus RTU. Two Ethernet ports support daisy-chain topologies, saving switch costs. Optional EtherCAT, encoder, and I/O cards expand functionality. The RS-485 port connects to legacy devices. All communication uses standard RJ45 connectors.
Selection Guide and Purchasing Advice
Before ordering, verify your motor voltage and horsepower match the 460 VAC, 2 HP rating. Confirm the A1 frame size fits your panel. Check if you need optional EtherCAT, encoder, or I/O cards.
