Toshiba vfd VF-AS3 series IoT Systems Solution.

Ideal for Plant & Process Control Application.The VF-AS3 can be connected with various devices through local area network, wireless network, and the Internet. It achieves data collection to know operational status and analyze system failure. This IoT-Ready function increase productivity and reduce total cost.

Toshiba frequency inverter VF-AS3 series is ideal for oil and gas, mining industry.

Multi ratings – excellent motor control performance.
The VF-AS3 has the multi ratings and can drive for various application with HD(150%- 60sec) and ND(120%-60sec). It is available for both heavy-load application and light-load application. The starting torque with sensor-less vector control is 200% with 0.3Hz or more. The VF-AS3 achieves high starting torque and high accuracy regenerative torque at low frequency.

Easy to set up with Auto-tuning function.
The VF-AS3 has the Auto-tuning function that automatically optimizes the drive parameters. The moment of inertia of machine and equipment can also be set easily by Auto-tuning function.
PM motor drive.
PM motor drive technology has been implemented in VF-AS3 as a standard feature. The VFAS3 can control both induction and permanent magnetic synchronous motors with/without feedback sensor, allowing them to use for the variety of purposes. The VF-AS3 can drive both interior permanent magnetic motor (IPM) and surface permanent magnetic motor (SPM).

Perfect for Conveyor and Crane Industry.

Embedded positioning control.
VF-AS3 has sensor / sensor-less position control with point to point, Pulse input and Orientation, which is suitable for applications such as processing machine for high precision control.
Excellent flexibility by My Function (logic function).
My function adds programming capability to the drive’s input/output signals without external relays or PLC (programmable logic controller). The function makes it possible to reduce the space and cost required for the system. My function has the relay sequence function that combines logic operation functions. The relay sequence function enables the drive to perform itself in 52 steps (4 steps x 7 units + 24 steps) without PLC. The processing speed is faster than control with PLC as the function uses internal data and signals directly.

Toshiba drive VF-AS3 series is perfect for Water & Wastewater Industry.

Multi pump control – maximum 10 pumps.
The VF-AS3 can drive multiple pump motors (maximum ten pumps) and save the power of water pump system by controlling each pump appropriately, realizing great cost reduction. Each pump is connected to commercial power via magnetic contactor which is controlled by relay output signal of the drive. There are 3 relay output terminals on the drive. Furthermore, two I/O extensions can be inserted to the drive. Each I/O extension has 3 relay output terminals, and thus a maximum of 9 relay output terminals can be used.
Space-saving and cost reduction by four embedded PID controllers.
VF-AS3 has four built-in PID controllers: two for drives (motors) and other two for other devices including heaters and valves. The built-in PID controllers are available at the same time for many purposes. It can help reduce cost and space because it can omit additional external PID controllers. The PID functions include temperature or pressure control of fan and pump, speed control of a winder, stop position control, etc.

Reliable safety function in Toshiba frequency inverter VF-AS3 series.

The VF-AS3 has STO (Safe Torque Off) function as standard and is highly reliable to cut off output in an emergency. The STO function brings the machine safely into a no-torque state and prevents it from starting accidentally. It complies with safety standard IEC 61800-5-2 and also achieves SIL3 level in IEC 61508 : 2010. In addition, the following safety functions are available as options:
- SS1 (Safe Stop 1)

- SLS (Safely-Limited Speed)
- SDI (Safe Direction)

Harmonics reduction in Toshiba drive VF-AS3 series.

The VF-AS3 is very friendly to a power supply system and peripheral equipment. The built-in dual DC reactor(*1) suppresses harmonic current and improves power factor. VF-AS3 complies with IEC61000-3-12 and achieves total harmonic distortion (THDi)≦48% without external reactor. (480V Class only)

High-frequency noise reduction in Toshiba vfd VF-AS3 series.

The built-in EMC filter suppresses high frequency noise. The filter is ideal for sites such as commercial facilities, offices and factories where attentions must be paid to peripheral devices. The VF-AS3 complies with EMC directive of IEC61800-3 Category C2/C3 without external filter. (480V Class only) In addition, the VF-AS3 has built-in UL Type 1 terminal box integrated with EMC plate.

Detachable operation panel.

The operation panel is detachable and easy to attach an external control console with door mounting kit. The optional panel is not required. The protection level of the keypad is enclosed type with door mounting kit, which means dust-proof and wash-down capable. The touch wheel has high sensitivity, which allows easy, smooth operation.

Wide, multi-language LCD screen (HMI).

The wide LCD screen (240 x 160 dots) displays multiple items at the same time, allowing easy setting of parameters. If the VF-AS3 trips, the panel will turn red in back light color, and it’s easy to recognize. The panel can be displayed in multiple languages including German, Italian, Spanish, French, Portuguese, Russian, Chinese and Japanese as well as English.
