Advanced Design and Functionality

•Major performance, operational and system advancements over DC.

•High frequency, silent operation from 0-300 Hz.

•24V – 80V battery systems, 350-650 A RMS 2 minute current ratings.

•Powerful operating system allows parallel processing

of vehicle control tasks, motor control tasks, and user

configurable programmable logic.

•Advanced Pulse Width Modulation technology provides efficient use of battery voltage, low motor harmonics, low torque ripple, and minimized switching losses.

•Tunable to any AC motor. Fully programmable for optimal match to individual AC motor characteristics.

•Built-in battery state-of-charge algorithms and hour meter.

•Field-Programmable, with FLASH downloadable main

operating code.

 

Superb Drive Control

•Field-oriented vector control, in conjunction with Curtis

tuned algorithms, provide peak torque and optimal

efficiency across the entire operating range.

•Extremely wide torque/speed range, including full

regeneration capability.

•Internal closed-loop speed and torque control modes allow for optimized performance – without an additional control box.

•Peak performance mapping technology lets you tune the maximum performance envelope in both “driving and braking” to your specific application through the use of OEM programmable parameters.

•The Torque Control Mode offers unique features and

provides seamless transitions and positive response under all conditions.

•Exclusive built-in pump control mode with superior response to hydraulic load changes.
