General Description
The MC1451A is a dedicated motion processor which functions as a complete chip-based step motor controller.
Packaged in a 2-IC chipset, this device performs trajectory generation and pulse and direction signal generation for use in a wide variety of stepper-based systems.
The MC1451A provides an optional third IC which allows incremental encoder signal input for position verification and on-the-fly stall detection.
The MC1451A is available in a one, a two, and a four-axis configuration.
The MC1451A is functionally similar to other PMD motion processors however it is dedicated to the control of step motors, instead of servo motors.
All of these devices provide sophisticated trajectory generation and synchronization features allowing the creation of complex motion sequences.
