The Drive Solution for
Total Harmonic Distortion (TDHE) can come from many sources, including computers,
fluorescent lights, copiers and six pulse drives. The W7, with Toshibaʼs patented 18 Pulse
Autotransformer design, removes this concern.
• Meets IEEE 519 Guidelines without Added 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.
- 400 HP Drive Only 42” Wide
- 24” Depth on All Sizes
�������
- Integrated Phase-Shifting Autotransformer
- Saves Real Estate on New Designs
- Easier Replacement of Old Drives
in Existing Facilities

Powerful, User-Friendly Operator Interface
The W7 advanced Electronic Operator Interface (EOI) is so intuitive the manual is usually
not needed to make drive setting adjustments. The W7 features menu driven programming
as well as direct access to all of the parameters. A built-in encoder makes programming
quick and easy.
• Easy Start-up Wizard
• Remote Mount up to 1,000 Feet
• Real Time Clock Option
• Flash Upgradeable EOI Software
• Display multiple parameter simultaneously
• Standard Keypad Design for Low Voltage and Medium Voltage Drives
Variety of Communication Options
In todayʼs fast-paced manufacturing world, coordinated systems require communications
from drive-to-drive and drive-to-system. Built-in ports and a variety of option cards provide
versatility in communication selection.
• Built-in RS232 / 485 and T
• Communication Protocol O
