IRMCF143S

IRMCF143S High Performance Position Servo Control IC Description IRMCF143S is a high performance Flash based motion control IC designed primarily for position servo applications based on an incremental encoder. IRMCF143S is designed to achieve low cost yet high performance control solutions for advanced inverterized servo motor control. IRMCF143S contains two computation engines. One is the Flexible Motion Control Engine (MCETM) for sinusoidal Field Oriented Control (FOC) of servo motors; the other is an 8-bit high-speed microcontroller (8051). Both computation engines are integrated into one monolithic chip. The MCETM contains a collection of control elements implemented in a dedicated computation engine such as Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, and Low loss SVPWM. The user can program a motion control algorithm by connecting these control elements using a graphic compiler. A unique analog/digital circuit and algorithm to fully support two...
