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

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 power section includes built-in bus choke (most ratings), 12-pulse input capability (most ratings), common DC bus capability and regeneration options.

This G7 (480V) allows motor operation at very long cable lengths, with peak voltage being 30% less than conventional drives. Motor bearing current is 50% less than standard drives, providing four times the bearing life. Audible motor noise is 20% less.
