The MC1231A is a dedicated motion processor which functions as a complete chip-based motor controller. Packaged in a 2-IC chipset, this device performs trajectory generation, servo loop closure, and sinusoidal commutation. The chipset inputs incremental encoder signals and outputs PWM or DAC-compatible motor command signals. The MC1231A is available in a one, or a two-axis configuration. The MC1231A is functionally similar to other members of PMD's 1st generation chipset family however it adds the ability to perform sinusoidal commutation of brushless motors. All of these devices provide sophisticated motion control capabilities allowing the creation of complex profile sequences with very low tracking errors.
