About the Varispeed-616G3
The Yaskawa Varispeed-616G3 is a high-performance inverter designed to convert three-phase AC commercial power supply to DC, and then to AC variable frequency voltage. This allows for precise speed control of three-phase squirrel-cage induction motors.
This manual covers models for both 200 to 230V (40 to 100HP / 30 to 75kW, 54 to 130kVA) and 380 to 460V (75 to 200HP / 55 to 160kW, 110 to 250kVA) power supplies.
