Yaskawa G7 DriveThe Yaskawa G7 drive is the ultimate performancesolution with increased speed and torque response to provide servo-likeperformance from an induction motor. The Yaskawa G7 drive has theworlds first 480V 3-level inverter architecture that eliminates orminimizes the installation problems associated with IGBT switching andprotects the entire motor-drive system.The 3-levelcontrol eliminates peripheral components typically required to solve installationproblems such as long motor cable leads, motor bearing life, audible noise, andcommon mode noise. The Yaskawa G7 drive performance makes it the ideal drive for high performancespeed, torque, or position control applications.The Yaskawa G7 drive is the total solution for the unconventional, extreme performanceapplications. With high-end response for speed and torque loops, the G7provides servo-like performance for superior motor control.

The Yaskawa G7 drive allows motor operation at very long cablelengths, meeting NEMA MG1 Part 31, with peak voltage being 30% lessthan conventional drives. With motor bearing current being typically50% less than standard drives, the G7 provides four times the motorbearing life.The Yaskawa G7 drive has three auto tuning methods to optimize motor control,including the new static auto tuning which does not require loaddecoupling nor motor rotation.The LCD operator displays 5 lines x 16 characters, in any of 7languages. The Yaskawa G7 keypad is intuitive and includes memory for parametersettings, making it easy to transfer settings from one drive to another.The YaskawaG7 / Configured packageprovides a G7 drive in either a NEMA 12, UL Type 1 (IP22 or IP54 depending on the exact rating) enclosure, with space for factory-mounted and wired options, such as reactors, filters, circuit breakers, fuses, network communications and I/O cards.

Programming and Software

Yaskawa G7 DriveThe Yaskawa G7 drive uses Drive Wizard software forthe PC and is available at no charge for upload, download, archiving,trending, and graphing.The Yaskawa G7 drive has a large programming feature set to handlesophisticated industrial applications. If the standard feature set does notmeet your specific requirement, the G7 can be programmed usingDriveWorksEZ.

This is a PC-based, object-oriented, graphical iconprogramming tool that is friendly to the user. The drive firmware canalso be modified by custom or pre-written application-specific modulessuch as Motion Control or Electronic Lineshaft.The G7 drive supports the industry’s preference for open networkarchitecture and connectivity with network choices such as EtherNet/IP,Modbus TCP/IP, Profibus-DP, DeviceNet, and others.The Yaskawa G7 is not intended for the simple, routine AC drive application, it isfor the challenges. The G7 drive offers the ultimate performance, thebest system protection, and the most flexible configurations of any driveavailable.
