Product data sheet for the Fuji Electric FRENIC5000G11S/P11S series inverters, detailing dynamic torque-vector control, specifications, and application…
This document provides technical specifications and features for the Fuji Electric FRENIC5000G11S and P11S series inverters. Key technology includes dynamic torque-vector control, which optimizes voltage and current vectors for maximum output torque and smooth acceleration. The system offers high starting torque and reduced motor wow at low speeds.
| Starting torque | 200% at 0.5Hz |
|---|---|
| Speed control range | 1:1200 |
| Speed control accuracy | 0.02% |
| Speed control response | 40Hz |
| G11S series power range | 1/4 to 600HP |
| P11S series power range | 7.5 to 800HP |
The primary control technology is dynamic torque-vector control, which performs high-speed calculation to determine the required motor power for the load status.
The P11S series is designed for fans and pumps, which are classified as variable torque loads.
Yes, it includes an on-line tuning system to continuously check for variation of motor characteristics during running for high-precision speed control.
