Development System Slashes Time To Design Motor Controls April 2003 Issue Published Date: April 01, 2003
Promising to slash the time needed to design motor controls from several weeks to just days, the IRACS201 development system employs the Accelerator Design Platform to achieve a design flow that requires no coding to configure motor control algorithms. The platform includes: a mixed signal motion control chipset; a FPGA-based, configurable DSP offering parallel processing capabilities and customizable peripherals; high voltage ICs for gate drive and current sensing functions; and an IGBT-based power inverter stage. The bundled software includes ServoDesigner, a Windows-based configuration tool for mapping internal registers to configure motor type, tune control parameters, monitor/diagnose internal signal waveforms, and more. The development system reportedly enables an advanced field control (FOC) and PWM algorithm loop to be executed in under 4 µs versus as much as 15 to 20 µs for a programmable DSP-based control loop. The IRACS201 price of $9,500 includes a 1.5-kW servo amplifier platform with pre-loaded code and ServoDesigner. For more details, contact Wayne Yoshida at INTERNATIONAL RECTIFIER, El Segundo, CA.
