• Outputs: Two analog output channels provide 10-bit resolution for monitoring, with signals from 0-20 mA, 4-20 mA, or 0-10 VDC.
• Discrete I/O: The drive features 8 sinking/sourcing digital inputs (24 VDC) and 3 relay outputs (Form C and Form A) for external control.

Physical Characteristics and Environmental Tolerances

• Enclosure and Frame: This UL Type 1 drive uses a compact A2 frame size, rated IP20 for protection against finger contact and dust.
• Temperature Range: It operates reliably in ambient temperatures from -15 to 50 degrees Celsius, ensuring performance in varied industrial settings.
• Built-in Components: The unit includes a built-in DC reactor, EMC filter, and conduit box to simplify installation and meet compliance standards.
• Dynamic Braking: This model features integrated dynamic braking, eliminating the need for external braking units in most applications.

Frequently Asked Questions

• What control modes does the Toshiba VFAS3-4075PC support? The Toshiba VFAS3-4075PC supports V/Hz, Flux Vector Control (FOC), and encoder-based torque control. This flexibility allows you to optimize the drive for simple fans or precise positioning tasks.
• Does this model include a built-in braking resistor? The VFAS3-4075PC includes an integrated dynamic braking transistor, but you may need to add an external braking resistor for high inertia loads or frequent deceleration cycles.
• What is the frame size of this drive? This model uses the A2 frame size, which offers a space-saving design ideal for 10HP applications with limited panel space.
• Is this drive suitable for permanent magnet motors? Yes, the AS3 series drive, including model VFAS3-4075PC, is specifically designed for use with both three-phase induction motors and permanent magnet AC motors.
• What is the difference between UL Type 1 and open frame? UL Type 1 provides finger-safe protection (IP20) and is suitable for standalone installations, while open frame requires mounting inside an electrical cabinet.
• What are the communication options available? This model features two Ethernet ports (RJ45) supporting EtherNet/IP and Modbus TCP, and one RS-485 port (RJ45) for Modbus RTU. It also offers a non-secure web server for basic monitoring.
• What is the overload capacity of this drive? The drive provides 150% overload capacity for 10HP applications (16.5A) and 120% overload capacity for higher momentary loads up to 23.5A.
