Servo Processor

The servo processor controls all of the plotter actuators. Executing the commands issued by the main processor, it reads the carriage and roller position from the processor support ASIC and writes the needed control data to the PWM (Pulse Width Modulation) generators in that ASIC. Through a serial link, the servo processor sends nozzle5timing data to, and receives carriage5sensor data from, the carriage processor.

Processor Support ASIC

The processor support ASIC provides support for the servo processor, and an interface between the main processor and the servo processor.
