Yaskawa VFD drives are designed to minimize harmful demand for input harmonic distortion. Yaskawa VFD drives up to 25 HP are available with optional 3% or 5% equivalent line impedance DC Bus Reactors. At 30 HP and above, Yaskawa VFD drives include 3% impedance as standard. Some Yaskawa VFD drives include a dual diode bridge rectifier which can be configured to accept 12-pulse (delta-delta and delta-wye secondary) transformer input. Yaskawa VFD drives can also be factory configured with an integral 18-pulse transformer. These packages are typically used to meet the most strict harmonic requirements at both drive input terminals and the point of common coupling.

Yaskawa VFD drives are factory-programmed and ready to run. An LCD interface enhances ease of use with its multiple language support and parameter copy feature that allows duplication of settings between drives. In addition, a portable USB Copy Unit (1000 series only) provides a very convenient method of desktop configuration transportable to the factory floor. All Yaskawa VFD drives have a split cover for easy access to the power and control terminals. The power terminal compartment easily accommodates bend radius for cable connections. Control wires are connected to a detachable terminal board for ease of installation and maintenance.

Detachable cooling fans are easy to replace and on/off fan control can extend operating life. Accumulated operation time and cooling fan run time are recorded and can be displayed for preventive maintenance programs. Start-up and configuration are simplified by the intuitive programming menu and start-up procedure. DriveWizard® Industrial is a PC-based support tool for drive commissioning and maintenance. It provides a way to operate the drive, change parameters, upload and download parameters, monitor and graph parameters, provide status and troubleshooting data, and utilize a host of additional features with built-in help menus.

Yaskawa VFD Drives Product Overview

The Yaskawa A1000 is a multi-purpose VFD drive delivering up to 1000 horsepower, and provides Yaskawa’s highest level of vector performance including precise control of both induction and permanent magnet motors. The Yaskawa A1000 VFD drive is a full featured drive, providing outstanding quality, performance, flexibility, and environmental friendliness through 1000HP. Enjoy network communications, feedback, and expandable I/O to control anything from simple fans and pumps to complex machines. For new installations or retrofits, the Yaskawa A1000 VFD drive provides a single robust solution, regardless of the application.

The Yaskawa G7 VFD drive is the ultimate performance solution with increased speed and torque response to provide servo-like performance from an induction motor. The Yaskawa G7 VFD drive has the world’s first 480V 3-level inverter architecture that eliminates or minimizes the installation problems associated with IGBT switching and protects the entire motor-drive system. The Yaskawa G7 VFD drive performance makes it the ideal drive for high performance speed, torque, or position control applications. Several control modes are provided in the G7. In open loop vector mode, the latest flux observer algorithms extend speed range and provide maximum starting torque. In closed loop vector mode, 0.01% speed regulation and 1000:1 control range can be achieved. Zero-servo capability provides position control at zero speed.

The Yaskawa P1000 VFD drive is the next generation in Industrial Fan and Pump control, designed for those applications that are variable torque. Simplicity, intuitiveness, and user friendliness were the key factors in the Yaskawa P1000 VFD drive design. The Yaskawa P1000 VFD drive includes a powerful set of pre programmed fan/pump application macro’s allowing for quick and easy commissioning. With its advanced motor control algorithm along with the next generation IGBT technology, motor noise and drive packaging is reduced. The P1000 supports a wide range of network and control options providing for the most cost effective solution.

The Yaskawa J1000 VFD drive is a general purpose AC drive; its PWM design provides low motor noise and high starting torque, with a heavy duty current overload rating of 150% for 60 seconds and a normal duty current overload rating of 120% for 60 seconds. Volts per hertz control makes the Yaskawa J1000 VFD drive suitable for most general applications. The J1000 is feature packed, low cost and compact. The digital operator includes a 5-digit LED status display. The Yaskawa J1000 VFD drive has five multi-function digital inputs, one multi-function analog input, one multi-function digital output, and one multi-function analog output. An optional RS-422/485 Modbus RTU serial communication port is available. An ideal choice whenever low cost and small size are required.

The Yaskawa V1000 VFD drive is a high performance line of AC micro drives with low motor noise and high starting torque. It provides two control methods; Volts per hertz, and open loop current vector control for precise speed regulation and higher torque at lower speeds. The Yaskawa V1000 VFD drive is intended for either heavy duty applications or normal duty applications. The Yaskawa V1000 VFD drive is the perfect choice wherever high performance in a small size is required.
