Yaskawa G7 Drive

The Yaskawa G7 drive is the ultimate performance solution with increased speed and torque response to provide servo-like performance from an induction motor. The Yaskawa G7 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 3-level control eliminates peripheral components typically required to solve installation problems such as long motor cable leads, motor bearing life, audible noise, and common mode noise. The Yaskawa G7 drive performance makes it the ideal drive for high performance speed, torque, or position control applications. The Yaskawa G7 drive is the total solution for the unconventional, extreme performance applications. With high-end response for speed and torque loops, the G7 provides servo-like performance for superior motor control.

The Yaskawa G7 drive allows motor operation at very long cable lengths, meeting NEMA MG1 Part 31, with peak voltage being 30% less than conventional drives. With motor bearing current being typically 50% less than standard drives, the G7 provides four times the motor bearing life. The Yaskawa G7 drive has three auto tuning methods to optimize motor control, including the new static auto tuning which does not require load decoupling nor motor rotation. The LCD operator displays 5 lines x 16 characters, in any of 7 languages. The Yaskawa G7 keypad is intuitive and includes memory for parameter settings, making it easy to transfer settings from one drive to another. The Yaskawa G7 / Configured package provides 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

The Yaskawa G7 drive uses Drive Wizard™ software for the 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 handle sophisticated industrial applications. If the standard feature set does not meet your specific requirement, the G7 can be programmed using DriveWorksEZ™.

This is a PC-based, object-oriented, graphical icon programming tool that is friendly to the user. The drive firmware can also be modified by custom or pre-written application-specific modules such as Motion Control or Electronic Lineshaft. The G7 drive supports the industry’s preference for open network architecture 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 is for the challenges. The G7 drive offers the ultimate performance, the best system protection, and the most flexible configurations of any drive available.
