Product Introduction
When demanding industrial applications require precise motor control and high reliability, the FANUC VFAS3-4132KPC delivers exceptional performance. This Toshiba AS3 series AC drive is a high-performance unit designed for 460 VAC three-phase input and output, rated at 200 horsepower with 3-phase input and a continuous amperage rating of 250A. Its open frame enclosure (IP00) allows flexible panel or wall mounting in controlled environments.
Technical Specifications Breakdown
The VFAS3-4132KPC offers versatile control modes including V/Hz, FOC (Field-Oriented Control), encoder feedback, and torque mode, making it suitable for a wide range of motor types. Key electrical specifications include:
- Input/Output Voltage: 460 VAC nominal, three-phase
- Horsepower: 200 hp with 3-phase input
- Amperage Rating: 250A continuous; variable torque rating of 302A
- Control Modes: V/Hz, FOC, encoder or torque
- Output Frequency Range: 0.1 to 590 Hz
- Carrier Frequency: 1 to 8 kHz
The drive includes an integrated EMI filter and built-in DC reactor, reducing external component requirements. Safe Torque Off (STO) is standard, enhancing operator safety during maintenance.
Industry Applications
This high-performance drive excels in heavy-duty applications such as:
- Pumping Systems: Variable torque capability (302A) matches centrifugal pump demands, reducing energy consumption.
- Conveyor Lines: FOC mode provides precise speed control for material handling, improving throughput.
- Extruders and Mixers: Torque control mode maintains consistent product quality under varying loads.
Installation & Setup Guidance
Mount the VFAS3-4132KPC on a panel or wall using the A6 frame dimensions. Ensure adequate airflow around the open frame enclosure for cooling within the -15 to 50°C temperature range. Connect three-phase 460 VAC input to the screw terminals. An external dynamic braking unit is required for rapid deceleration. Use user-supplied external fuses for overcurrent protection. The drive accepts 4-20 mA, voltage, potentiometer, or pulse train input signals.
Maintenance & Reliability
Regular inspection of the built-in DC reactor and EMI filter ensures long service life. Verify proper operation of the Safe Torque Off (STO) function periodically. Keep the open frame free of dust and debris to maintain cooling efficiency. The relay outputs (one Form C and two Form A) provide reliable switching for external alarms or contactors.
Compatibility & Integration
The VFAS3-4132KPC includes two Ethernet ports (RJ45) supporting EtherNet/IP, Modbus TCP, and a non-secure web server, plus one RS-485 port (RJ45) for Modbus RTU Slave communication at up to 38.4 kbaud. Optional EtherCAT, encoder, and I/O cards expand connectivity. The drive works with 3-phase induction and permanent magnet AC motors.
Selection Guide & Purchasing Advice
Before ordering, confirm your application requires 200 hp at 460 VAC with 250A continuous current. Verify the A6 frame size fits your enclosure space. The VFAS3-4132KPC includes a built-in DC reactor and EMC filter, but requires an external dynamic braking unit. Contact SpareTechPLC for current lifecycle status and availability, as this model may be subject to obsolescence.
