G9 ASD
LOW VOLTAGE DRIVE
G9 ASD
A POwErful DrIvE SOlutION
The G9 low voltage adjustable speed drive is the most advanced,
severe duty drive ever offered by Toshiba. Designed with the
end-user in mind, this drive combines a rugged, proven power
platform with the latest in power devices and an advanced
micro-processor to provide users with a smarter, stronger, more
reliable drive with flexible application control.
Powerful Performance separates the G9 from the
competition. This drive offers one of the toughest overload
ratings in the industry. On ratings up to 100 HP at 460 V and
50 HP at 230 V, the G9 provides a continuous overload rating of
115% of its full-load amp and 150% for up to two minutes. Above
these frames, the drive is rated for 110% of its full-load amp
rating for continuous operation and 150% for up to one minute.
Superior Control allows the user ultimate flexibility. The G9 can operate using open or closed-loop vector control volts/
hertz patterns. Toshiba’s advanced vector-control algorithm offers speed regulation of 0.1% sensorless and 0.02% with
motor encoder feedback. While operating in the feedback vector control mode, the G9 can generate 100% torque at zerospeed to hold the shaft stationary while the motor is stopped. The G9 drive also offers advanced torque control operation with
high torque accuracy and the ability to switch on-the-fly between speed and torque modes.

f Plain-English LED/LCD Interface Startup Wizard allow for quick, user-friendly
programming and easy modification of the expanded parameter set. The keypad is able
to store parameter sets which permit the user to set up multiple drives using these saved
parameters. In addition, a built-in fault-logging chip records faults in the keypad memory.
These records contain time and date stamps as well as detailed information about
operation at the time of the fault
My Function f , Toshiba’s proprietary programming feature, allows the user to utilize
logic-type programming without the expense of a micro PLC. The user is given access
to read all analog and digital inputs and outputs, as well as the ability to monitor and
perform data comparisons. When programmed in a user-defined logic sequence, the
use of this data will allow a higher level of process control not normally seen in an
adjustable speed drive. These functions, along with timers, counters, and comparators,
allow the G9 to perform tasks above and beyond simply running a motor
Eight Digital Inputs & Three Digital Outputs f are an integral part of the G9’s
versatility. Each of these inputs/outputs can be programmed to any 1 of more than
60 possible functions. When used in conjunction with My Function programming, the
capabilities of these terminals are virtually limitless. Additionally, the G9 is setting a new
industry standard by providing an isolated analog input (4 to 20 mA) on its standard
terminal strip.
A Built-In Proportional/Integral/Derivative (PID) Control Algorithm f
provides regulation of critical processes. High and low speed limits, deviation limits,
online switching, and a built-in sleep function are included to enhance the flexibility and
reliability of PID process control
