TOSHIBA G9

POWERFUL... ADVANCED... VERSATILE...

The G9 adjustable speed drive is
the most advanced severe duty
drive ever offered by Toshiba. It is
a blend of a robust power platform
and a state-of-the-art control
scheme. With its 115% continuous
overload rating and its dual
32-bit processor controls, the G9
provides the ability to operate the
toughest of applications while
still maintaining a high level of
control.

POWERFUL

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-y 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.
