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
