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. Withits115%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-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.
