toughest of applications while

still maintaining a high level of

control.

POWERFUL

G9 Family

The G9 drive has the highest

overload capability available. It is

rated at 115% continuous current, 150% up to 120 seconds, and 280% instantaneous

current. The Motor-Over-Flux-Braking Technology allows the G9 to provide as much as

25% of its rated power for use in stopping a heavy or high inertia load without dynamic

braking resistors.

The G9 can operate in open or closed loop controls. Toshiba's advanced vector control

algorithm offers speed regulation of 0.1% sensorless and 0.01% with motor or process

feedback. The G9 has the ability to switch on-the-fly between speed, torque, or position

control modes. In feedback vector control mode, the G9 generates motor breakdown

torque to hold the commanded position even while the equipment is stopped.
