50 Years of AC Drive Technology

Sixth Generation - GPD 506/P5. The newest generation of adjustable frequency ac drives. The GPD 506/P5 is a special purpose drive with application specific features that add significant "more-for-less" benefits.

• Alpha/numeric operator...Full function LCD English language operator and keypad with easy-to-read 16 character two-line format display. Easy input and monitoring of operating parameters.
• Built-in PID control...Eliminates cost of external device. Full featured scalable PID feedback with display and an inverse signal function.
• Sleep function...Standard PID feature which allows certain operations to be blocked out when their demands fall below levels which produce measurable benefits. Reactivated automatically when needed.
• Energy savings control...Automatic output voltage adjustment in response to actual motor loading. Real-time energy savings based on motor algorithms. Increases motor efficiency by several percent.
• Built-in power consumption monitoring...Built-in kW hour and kW display eliminates the need for external signal conditioner.
• Maximum network architecture...HVAC Serial Communications links to either Metasys, Apogee, Echelon LonWorks or ModBus RTU.
• Fire Stat control...Unique to the industry, this standard feature enables building management software to determine drive operation during a crisis.
• Under torque detection...Alerts the operator to conditions such as loss of load or broken fan belts.
• Constant torque capability...Enhanced slip compensation gain with 6 multispeed settings.
• Dual-bridge, 12-pulse rectification...By using a zig-zag input transformer with dual secondary, input current harmonic distortion factor can be reduced over 90%.
• ASICs...Application Specific Integrated Circuitry increases reliability.

Designed for Special Purposes. The GPD 506/P5 is designed specifically for applications where overload and starting torque requirements are well known, and where excess capacity is wasted investment. Common applications of this type include fans, centrifugal pumps, commercial laundry machines, grinders, buffers, low-viscosity mixers, centrifuges and saws.

Yaskawa's design specifications for the GPD 506/P5 were selected to provide application-specific benefits. PID control, energy saving control mode, power data display, communications port, bypass configurations, NEMA 1/4/12 enclosure choices, current harmonic reduction choices, and the right collection of I/O signals and interface controls lead to one conclusion &endash; the GPD 506/P5 is the best choice in special purpose ac drives.
