VFAS3-4185PC 25 HP AC Drive | AS3 Series VFD Toshiba

Toshiba VFAS3-4185PC AS3 Series Drive with Dual Overload Ratings

Flexible Dual Rating and Advanced Motor Control

• The drive features a dual rating through a simple parameter change. For heavy-duty applications requiring 150% overload for 60 seconds, it delivers 25 HP at 39.2 A. For normal-duty applications with 120% overload, it provides 30 HP at 46.3 A.
• It supports versatile control modes including V/Hz, Flux Vector Control (FOC), and torque control with encoder feedback. This flexibility allows the Toshiba VFAS3-4185PC to handle diverse applications from simple conveyors to precision positioning tasks.
• Integrated dynamic braking enhances system performance by managing regenerative energy. This feature improves reliability and extends the lifespan of your equipment during deceleration cycles.
• Safety is paramount with embedded STO (Safe Torque Off) compliant with IEC 61800-5-2 and SIL3 level in IEC 61508. This ensures maximum personnel safety during maintenance without removing main power.

Built-in Communication and Smart Features

• Standard networking includes built-in dual-port Ethernet IP and two-wire or four-wire RS485 connectivity. This allows for seamless integration into new or existing factory control architectures with EtherNet/IP and Modbus protocols.
• The embedded web server provides easy access for monitoring and configuring the drive via a standard browser. This simplifies diagnostics and setup without needing proprietary software or cables.
• A unique QR code display offers instant access to additional parameter information and fault troubleshooting. Simply scan the code with a mobile device for quick guidance during commissioning or maintenance.
• The real-time clock enables past trip monitoring and calendar functionality. This helps you track fault history and schedule events based on time and date for improved process management.

Comprehensive I/O and Control Specifications

• The drive includes eight programmable digital inputs for flexible control configuration. Three programmable digital outputs consist of one Form-C relay and two Form-A dry contact relays for status indication and control.
• For analog signals, it features three programmable analog inputs: one accepts 4-20 mA, one accepts 0-10 VDC, and one provides +10 VDC for potentiometer reference. Two programmable analog outputs can deliver either 4-20 mA or 0-10 VDC signals.
• The analog inputs offer 11-bit resolution for precise feedback and control. The analog outputs provide 10-bit resolution for accurate monitoring of drive performance parameters.
• The output frequency range spans from 0.1 Hz to 590 Hz, accommodating various motor speeds and process requirements. The carrier frequency is programmable for optimal performance.
