Servo Processor System
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 nozzleĆtiming data to, and receives
carriageĆsensor data from, the carriage processor.
The processor support ASIC provides support for the servo processor, and an interface
between the main processor and the servo processor.
