The EZ Piezo Servo was designed to allow the rapid implementation of Position Control using the Nanomotion** HR1-1-S3 or Similar Motor .
The fully intelligent controllers, measuring just 2.25 x 2.25 . The Nanomotion** HR1 Motor, 9pin DSUB connector plugs directly into the Controller. A single 4 wire bus, containing 2 power wires and two communications wires, links up to 16 such Piezo motor controllers in a daisy chain. (See Wiring Diagram). Commands can be issued from any serial terminal program (such as HyperTerminal) or from the EZ Servo/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 EZ Servo 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.
Using our Starter Kits , a first time user is able to make The HR1 Piezo Motor servo intelligently in less than half an hour. (See Wiring Diagram)
