32’’
Small Footprint
Today, the high cost of real estate and space constraints in
existing facilities make size an important factor in drive selection.
Toshiba responds with the GX7. The GX7 provides proper cooling
of internal electronic components to ensure optimum performance
and durability even in a small footprint enclosure.
. 500 to 800 HP; Only 32 Inches Wide
. 95 Inches High and 30.5 Inches Deep
. Saves Real Estate on New Designs
. Easy Replacement for Dated Drives in Existing Facilities
95’’
Industrially Hardened
The GX7 Series has the highest overload capability available
for a 600 V, 500 HP and above drive. Rated at 110% continuous
current, 130% up to 120 seconds, the GX7 can withstand load
conditions that would cause other drives to fail.
The GX7 is ready for continuous, trouble-free operation in the
most demanding manufacturing environments. In addition, it is
designed for an operating environment of -10 to 40°C at elevations
of -1000 to 1000 meters.
Variety of Communication Options
In the fast-paced manufacturing world, coordinated
systems require drive-to-drive or drive-to-control system
communication. Toshiba’s GX7 comes standard with
RS232/485 and TTL communication ports. In addition to
the standard communications features, Toshiba offers a
number of popular industrial communication protocol options
including: Modbus RTU, Modbus Plus, Ethernet IP, Profibus
DP, DeviceNet and Johnson Controls Metasys N2.

Proven Technology
Advanced Electronic Operator Interface
The GX7’s Electronic Operator Interface (EOI) features a multi-line, graphics-capable,
plain English, back-lit LCD. The EOI is so intuitive that the manual is usually unneeded
to make setting adjustments. The GX7 has menu-driven programming as well as direct
access to the parameters. A high reliability rotary encoder makes programming easy.
Startup Wizard helps facilitate initial programming.
Configurables
• Easy to Remote-Mount the Display (up to 1000 Feet)
• Real-Time Clock Option (Stores up to 100 Past Faults with Date and Time Stamp)
• Graphics-Capable LCD to Aid in Diagnostics
• Flash-Upgradeable EOI Software
• Help from Toshiba Customizing Application-Specific Wizards
Standard Keypad Design for Low Voltage and Medium Voltage Drives
Monitor Software
The free monitor software allows the user to monitor and control critical operational
parameters using serial communication. The software contains real-time graphing, a very
useful tool for data analysis which allows files and tables to be created with the software
from the obtained data.
Process Control
The built-in Proportional/Integral/Derivative (PID) control loop provides regulation of
many processes without the need for external devices. Deviation limits, online switching,
and delay filtering functions are included to enhance the flexibility and reliability of PID
process control.
