Simple, compact, powerful drive that's easy to set up
The drive is smaller than a standard quadrature encoder, measuring 0.95 3 1.4 3 0.6 inch (24 3 35 3 15.24 mm). It can control motors at 1.5A continuous, from 12 to 40V, accepting high-level commands from a serial port. Most first-time users can get the servo motor running intelligently in less than half an hour. With most motors measuring less than 1.5 inch in diameter, the drive needs no tuning, and users can dasiy-chain as many as 16 drives on a single four-wire bus (two power, two communications). Users can store programs in an onboard EEPROM, so there's no need for a PC connection, and it can execute commands on power-up. HyperTerminal, or other-serial terminal programs. The EZServo/stepper Windows application can also issue commands. It communicates with intuitive ASCII commands and is compatible with Cavro DT or OEM-protocol devices.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
