AllMotion: Servo Motor Controller Driver EZSV10

Servo Motor Controls

The EZServo was designed to allow the rapid implementation of Brush DC motor solutions in products requiring automation.

These fully intelligent controllers, measuring just 0.95" x 1.4", require little or no tuning when used with most motors measuring less than 1.5" in diameter. (Default PID values are robust and are stable with most motors). A single 4 wire bus, containing 2 power wires and two communications wires, links up to 16 such DC motors in a daisy chain (see wiring diagram). Commands can be issued from any serial terminal program (such as HyperTerminal) or from the EZServo Windows application.

The Commands are intuitive and simple. For example, the command A10000 will move the servo motor to Absolute position 10000. This communications protocol is compatible with devices that use the Cavro DT or OEM protocol.

Using Starter Kits, a first time user is able to make a Brush DC Servo Motor move intelligently in less than half an hour.
