Servo Motor Controller Module, 300 Series


The 300 series was designed to allow the rapid implementation of Brushless DC motor or Brush DC Motor solutions in products requiring automation.


The fully intelligent controllers, measuring just 2.25 " x 2.25 ", are require little or no tuning when used with most motors measuring less than 3 " 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 BLDC or Brush 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/Stepper 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)


The 300 series is also capable of stand alone operation with no connection to a PC. It can be set to execute a preset string of commands upon power up (i.e. Only power is required in this mode). The Commands include nested loops and execution halt pending a switch closure, which is useful in stand alone applications.
