General Info
G7 inverter is a high-class inverter of Yaskawa. This innovative drive utilizes 3 level control to offer the best solution for challenging installations. 3 level technology minimizes drive induced problems associated with long motor cables and premature motor bearing failures. In addition, overall electrical noise is greatly reduced, resulting in the most problem free installations. Not only does the Yaskawa G7 deliver this exclusive advantage, but it also provides high flexibility and excellent vector performance for control of speed, torque, and position, available in ratings through 500HP.
