Toshiba VT130H9U4055 H9 Adjustable Speed Drive, 5HP 460V 3PH

The Toshiba VT130H9U4055 H9 Adjustable Speed Drive is a heavy-duty industrial AC drive engineered to deliver precise, reliable speed control for 5 HP, three-phase 460 V motors. Designed as part of Toshiba’s H9 series, it combines a rugged power platform with advanced control technology to support demanding automation applications where uptime and control accuracy are critical. 

Why It Helps
By converting fixed-frequency line power into a controlled output, the VT130H9U4055 allows operators to optimize motor speed, torque, and process stability without mechanical throttling. Its vector control algorithms support high starting torque and tight speed regulation, while integrated PID control and “My Function” logic reduce the need for external controllers. This simplifies panel design, enhances system flexibility, and helps improve overall energy efficiency in industrial processes. 

Key Highlights

• H9 series heavy-duty design
  Built on a proven Toshiba power platform, the H9 drive family is known for robust construction suitable for severe-duty industrial environments, supporting continuous operation in demanding applications. 

• Advanced vector and V/f control
  The drive supports volts-per-hertz and advanced vector control modes for precise speed regulation and strong low-speed torque, helping maintain stable motor performance across a wide operating range. 

• Integrated process control capability
  Built-in PID control allows direct regulation of process variables such as pressure or flow from the drive, while Toshiba’s “My Function” logic programming feature enables micro-PLC-like control without additional hardware. 

• Motor-over-flux braking
  Toshiba’s motor-over-flux braking technology helps decelerate high-inertia loads without requiring an external dynamic braking resistor, simplifying installation and reducing panel component count. 

• User-friendly operator interface
  The removable electronic operator interface includes an LCD and LED display, navigation keys, and a rotary encoder, supporting quick setup, parameter copying between drives, and convenient local operation. 

• Flexible I/O and communications
  Multiple programmable digital inputs, relay outputs, and analog I/O support integration into a variety of control schemes, while built-in RS-485 and optional fieldbus cards (such as DeviceNet, Profibus DP, or Ethernet-based options) enable networked control and monitoring. 

System Compatibility
The VT130H9U4055 is intended for use with suitable 5 HP, three-phase 460 V induction motors in systems supplied from a 380–480 V three-phase source. It is typically installed in NEMA 1 environments such as motor control centers or enclosed control panels, and its flexible I/O and communication options help it integrate into existing PLC or DCS architectures. 

Applications
Common applications include pumps, fans, blowers, conveyors, and other industrial machinery where variable speed operation, controlled acceleration and deceleration, and process feedback control are needed. In these applications, the Toshiba VT130H9U4055 H9 Adjustable Speed Drive offers dependable motor control performance and practical integration features that support long-term system reliability and productivity.
