Description

At boot time, the Drive Module and PMI processor use an asynchronous master-slave protocol to transfer the PMI operating system and establish synchronized communication. The PMI processor is the master, and commences by requesting its operating system. The Drive Module responds by downloading the operating system in a special message, containing up to 256 byte packets. When the operating system transfer is complete, the Drive Module sends a configuration message and a gain message. The configuration message contains information that fixes the communication frequency at 4 mS. Once the Drive Module and PMI processor have synchronized communications, normal Set Point/Feedback data transfer can begin.

The synchronized protocol is called “Set Point/Feedback Data Exchange”. The drive module sends set point data to the PMI processor. The set point data contains reference data, for drive control, and a time stamp. This time stamp enables the PMI processor to calculate what the proper time is for the next feedback message. The PMI processor sends feedback messages to the Drive Module. The feedback messages contains data about drive operation.
