Product Overview
When your application demands precise motor control and robust performance, the FANUC VFAS3-4110PC delivers. This Toshiba AS3 series AC high-performance drive handles 460 VAC, 15hp with 3-phase input, making it a reliable choice for industrial automation. It supports multiple control modes—V/Hz, FOC, encoder, or torque—so you can match the drive to your specific process needs. The integrated dynamic braking and built-in EMC filter simplify installation and reduce external component requirements.
Technical Specifications Breakdown
Key parameters define the VFAS3-4110PC's capabilities. The nominal drive input and output voltage is 460 VAC, with 3-phase input and output. Horsepower rating is 15hp with 3-phase input, and the amperage rating is 23.5A (variable torque rating 31.7A). Control modes include V/Hz, FOC, encoder, or torque, offering flexibility for different motor types. The enclosure is UL Type 1 with an IP20 rating, suitable for indoor panel or wall mounting. Communication ports include two Ethernet RJ45 and one RS-485 RJ45, supporting EtherNet/IP, Modbus TCP, Modbus RTU Slave, and a non-secure HTTP webserver. Port speeds are 10/100 Mbps for Ethernet and up to 38.4k baud for RS-485.
Industry Applications
This drive excels in applications requiring variable speed control of 3-phase induction and permanent magnet AC motors. Common uses include conveyors, pumps, fans, and machine tools. The VFAS3-4110PC's V/Hz mode suits fan and pump applications, while FOC or encoder mode provides high torque accuracy for positioning or tension control. The integrated Safe Torque Off (STO) enhances safety in automated lines. For example, in a packaging line, the drive's 0.1-590 Hz output frequency range allows precise speed adjustments, reducing mechanical wear and improving product consistency.
Installation and Setup Guidance
Mount the VFAS3-4110PC on a panel or wall using the A3 frame. The drive includes a built-in DC reactor, EMC filter, and conduit box, simplifying wiring. Use screw terminals for connections. Ensure the ambient temperature stays within -15 to 50 deg C. The carrier frequency range is 1-16 kHz; adjust based on motor cable length and noise requirements. The drive accepts 4-20 mA, voltage, potentiometer, or pulse train input signals. Analog inputs (3 channels) accept 0-20 mA or 4-20 mA current and +/-10 VDC voltage. Analog outputs (2 channels) provide 0-20 mA or 4-20 mA current and 0-10 VDC voltage. Discrete inputs (8 points, 24 VDC, sinking/sourcing) and discrete outputs (3 relay points, 250 VAC/30 VDC) handle control and status signals.
Maintenance and Reliability
Regular inspection of the VFAS3-4110PC ensures long service life. Check the cooling fan and air filters for dust buildup. Verify that the ambient temperature stays within the rated range. The integrated dynamic braking reduces wear on external braking resistors. Since the drive includes a battery (UN3091, lithium button cell CR2032), replace it periodically using the recommended D0-MC-BAT battery. Follow the manufacturer's guidelines for safe operation. The UL Type 1 enclosure protects against dust and incidental contact, reducing maintenance frequency.
Compatibility and Integration
The VFAS3-4110PC integrates seamlessly with industrial networks. The two Ethernet ports support EtherNet/IP and Modbus TCP for high-speed communication. The RS-485 port handles Modbus RTU Slave for legacy systems. The drive works with 3-phase induction and permanent magnet AC motors. Optional EtherCAT, encoder, and I/O cards expand functionality. The built-in EMC filter and DC reactor reduce external filtering needs. The drive's user sequence programming language allows custom logic without a separate PLC.
Selection Guide and Purchasing Advice
Before ordering the VFAS3-4110PC, verify your system voltage (460 VAC, 3-phase) and horsepower requirements (15hp). Confirm the enclosure type (UL Type 1, IP20) suits your environment. The A3 frame size determines mounting space. SpareTechPLC stocks this drive and can advise on availability and lifecycle status.
