General Description
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.
