Toshiba VFAS3-4370PC High-Performance Drive | 460VAC

Toshiba VFAS3-4370PC AS3 Series Drive for Reliable Industrial Automation

Advanced Motor Control and Performance Features

• The drive offers versatile control modes including V/Hz, Flux Vector Control (FOC), and torque control with encoder feedback. This flexibility allows the Toshiba VFAS3-4370PC to handle everything from simple pumps to complex precision conveying tasks.
• It provides a substantial output with a variable torque amperage rating of 88 A. The wide output frequency spans from 0.1 Hz to 590 Hz, accommodating various motor speeds and process requirements with ease.
• Integrated dynamic braking and a built-in DC reactor enhance system performance and reliability. These components effectively manage regenerative energy and improve power quality, extending the lifespan of your equipment.
• Safety is paramount with the built-in Safe Torque Off (STO) function. This feature ensures personnel safety during maintenance by preventing motor start-up without removing main power from the VFAS3-4370PC.
• The carrier frequency ranges from 1 kHz to an industry-leading 16 kHz. This wide range allows for quieter motor operation and helps reduce audible noise in sensitive environments.

Integrated Communication and I/O Specifications

• Standard networking includes two Ethernet ports supporting EtherNet/IP and Modbus TCP, plus one RS-485 port for Modbus RTU. This dual-port design allows for easy integration into new or existing factory control architectures.
• For precise process feedback, the analog inputs offer an 11-bit resolution and accept signals from 4–20 mA or ±10 VDC. The drive features three configurable analog input channels to monitor various sensors and transmitters.
• Discrete control includes eight 24 VDC sinking/sourcing inputs. The three relay outputs consist of one Form C (SPDT) and two Form A (SPST) relays, capable of switching up to 250 VAC or 30 VDC at 2 A per point.
• The built-in non-secure web server provides easy access for monitoring and configuring the drive via a standard web browser. This simplifies diagnostics and setup without needing proprietary software.
