Varispeed G7
3 Level control method
Ratings:
200 V CLASS 0.4 TO 110 kW
400 V CLASS 0.4 TO 300 kW
This innovative drive utilizes 3 level control to offer the best solution for challenging installations. Yaskawa is the only manufacturer to offer a low voltage drive with this architecture. 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 300kW
