Yaskawa AC Drive G7 Adjustable Speed Drives

Yaskawa AC Drive G7

The AC Drive G7: This amazing AC drive is the ultimate performance solution with increased speed and torque response to provide servo-like performance from an induction motor. In addition, the 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.

AC Drive G7 performance makes it the ideal drive for high performance speed, torque, or position control applications. Several control modes are provided. In open loop vector mode, the latest flux observer algorithms extend speed range and provide maximum starting torque.
In closed loop vector mode, 0.01% speed regulation and 1000:1 control range can be achieved. Zero-servo capability provides position control at zero speed.

The G7 drive has the world’s first 480V 3-level inverter architecture for total system protection. This patented design can eliminate peripheral components typically required to solve installation problems. The G7 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. Audible motor noise on the 480V G7 drive is 5-10dB (20%) less than the prior generation drive, even when operating at half the carrier frequency. Common mode current is half that of competitor drives.
