Product Overview
When reliable motor control is critical for your industrial process, the FANUC VFAS3-4007PC delivers. This Toshiba AS3 series AC high-performance drive handles 460 VAC input with 1 HP and 3-phase power. It supports multiple control modes including V/Hz, FOC, encoder, and torque mode. The A1 frame size and UL Type 1 enclosure make it suitable for panel or wall mounting in light industrial environments.
Technical Specifications Breakdown
The VFAS3-4007PC offers a robust set of electrical and I/O specifications. Its nominal drive input and output voltage is 460 VAC, with a current rating of 2.2A and variable torque amperage rating of 4A. The output frequency range spans 0.1 to 590 Hz, and the carrier frequency range is 1-16 kHz. For control, it provides 3 analog input channels (11-bit resolution, 0-20 mA, 4-20 mA, +/-10 VDC) and 2 analog output channels (10-bit resolution, 0-20 mA, 4-20 mA, 0-10 VDC). Discrete I/O includes 8 sinking/sourcing inputs at 24 VDC and 3 relay outputs rated at 250 VAC/30 VDC, 2A per point. Communication ports include two Ethernet RJ45 (10/100 Mbps, EtherNet/IP, Modbus TCP, web server) and one RS-485 RJ45 (up to 38.4k baud, Modbus RTU Slave).
Industry Applications
This drive excels in applications requiring precise speed and torque control for 3-phase induction and permanent magnet AC motors. Use it in conveyor systems, pumps, fans, and machine tools. The integrated Safe Torque Off (STO) function enhances safety in automated production lines. The built-in DC reactor and EMC filter reduce harmonic distortion and electromagnetic interference, making it ideal for installations with strict power quality requirements.
Installation & Setup Guidance
Mount the VFAS3-4007PC on a panel or wall using the A1 frame dimensions. Use screw terminals for all power and I/O connections. The user-supplied external fuse protects the drive. Connect the 3-phase input and output wiring per local codes. For communication, use standard Ethernet and RS-485 cabling. The built-in dynamic braking resistor handles regenerative energy from decelerating loads. Ensure ambient temperature stays between -15 to 50 deg C and enclosure is IP20 rated.
Maintenance & Reliability
Regular inspection of the cooling fan and air filters keeps the drive running reliably. Check terminal connections for tightness periodically. The integrated EMI filter and DC reactor reduce electrical stress on components. With proper care, this drive provides long service life in demanding industrial environments. The built-in STO function adds a layer of safety without external components.
Compatibility & Integration
Integrate the VFAS3-4007PC into existing automation systems using EtherNet/IP or Modbus TCP for high-speed data exchange. Use Modbus RTU Slave over RS-485 for legacy controller connections. The drive accepts analog signals (4-20 mA, voltage, potentiometer, or pulse train) and provides PWM output. Optional EtherCAT, encoder, and I/O cards expand its capabilities for advanced motion control applications.
Selection Guide & Purchasing Advice
Before ordering, verify your motor voltage and horsepower match the drive's 460 VAC, 1 HP rating. Confirm the 3-phase input supply and check that the A1 frame fits your panel space.
