Truly Designed for
Total Harmonic Distortion (THD) can be caused by multiple factors including: computers,
fluorescent lights, copiers, and six-pulse drives. With Toshiba’s patented 18-Pulse
Autotransformer design, the QX7 removes distortion that would normally be generated by
a six-pulse drive.
• Meets IEEE-519 Guidelines without Adding Filters
• Produces a Ripple-Free Voltage on DC Bus
• Clean Sinusoidal Input Current Waveform
• Up to 60% Reduction in Transformer Losses

Small Footprint
The high cost of real estate and constraints
of existing facilities make size an important
consideration in drive selection.

User-Friendly
The QX7 keypad is rugged and reliable, but also easy to use. The LCD true-English display
makes it easy to read and program. Menu-driven parameters and quick set-up keys allow the
operator to program the drive with the smallest amount of keystrokes possible. On top of all
these great keypad features, the QX7 also comes with Toshiba windows-based software.

The Fire Speed Circuit allows you to run at a preset speed during a smoke purge.
The Damper Permissive Function can be utilized to protect your ductwork from over
pressuring. In addition, the PID settings will keep your system balanced.
Communication Options
The QX7 is easily integrated into your control system, giving you powerful information access
and control capabilities while reducing installation costs.
Drive Information: Integrating the drive into your control system allows you access to monitor,
control, and diagnostic data.
