    Improve throughput with advanced open-loop motor control algorithms
    • Rotor Flux Control (RFC-A) gives maximum stability and control of induction motors at all powers.
    • S-ramp accel / decel profiling provides smooth speed transitions to minimize “jerk”
    • 180% motor overload suitable for heavy industrial machinery applications

    Install and configure quickly and easily
    • Simple fixed LED keypad
    • Useful parameter guide located on the front of the drive
