3 UPM-28 OEM Evaluation Kit Instruction Manual 1.0 Introduction The contents of this kit are intended to be used as an evaluation tool for engineers interested in learning more about the performance and operation of DTI s UPM-28 piezoelectric motors (piezomotors). The UPM-28 is a technically advanced piezomotor designed for precise positioning and other applications. The UPM-28 combines high performance and excellent quality with an affordable low cost. The electronic driver PCB for the piezomotor is included in the kit, together with cables and a 12 DC power supply. Figure 1. Electronic PCB driver Page 2

Model UPM Properties Some of the unique properties of the UPM-28 include: Modern reinforced engineered thermoplastic design provides reliability and low cost Superior precision and resolution Ultra-Fast response time with superior start-stop characteristics High torque for size Designed for direct drive applications Stepping and Continuous mode of operation Six orders of magnitude speed dynamic range When not energized, the motor serves as a brake and consumes zero power Silent operation in continuous mode Low voltage and decreased possibility for electrical arcing Page 3

5 3.0 Unpacking and Preparation After unpacking the UPM-28 evaluation kit, the items should be checked against the Parts List shown in Table 1. If any items are missing contact DTI immediately for replacement parts.

7 5.0 Operation and Control of the Piezomotor 5.1 Connecting the Power Supply Connect the 12V Power Supply to the Power Supply Connector located on the electronic driver PCB (Figure 1). Connect the other end of the 12V Power Supply to an appropriate wall power socket. 5.2 Connecting the Driver Board The piezomotor connects to the driver board by a connector on the end of the motor wire. This connector mates with the corresponding connector on the electronic driver PCB. The connectors can only be joined in one possible orientation. Press the connector gently in place so that it is flush with the edges of the receptacle on the driver PCB. 5.3 Operation of the Motor and Driver Board The electronic driver PCB generates the drive signals required by the piezomotor. Motion is created causing the rotor to rotate. The design enables travel in only one direction. Manual control of rotation is achieved by pushing the button on the driver board. 5.4 External Control The driver board can be controlled using an external signal source. Control signals are applied to Pin 1 or Pin 2 on the External Signal Connector (1,2,3) Fig. 1, Pin 3 is the common wire. The unused wire must be held at TTL high or be left open. The control signals applied to Pins 1 or 2 must be TTL compatible. A high level (1.8 to 12 Volts) disables travel, a low level (0 to 0.8 Volts) enables travel. 5.5 Stepping and Continuous Modes The mode of travel, stepping or continuous, depends on the type of signal applied to the External Signal Connector (1,2,3) Fig. 1. A constant high level (D.C.) signal will result in continuous motion at maximum speed. A pulse or pulse train will result in stepping operation. In the stepping mode (PWM mode), the size of each step is determined by the pulse duration, and the speed of travel is determined by the pulse repetition rate. The minimum pulse duration is around 30 microseconds. The maximum repetition rate F, measured in Hertz, for a selected pulse duration T, measured in seconds, is determined by the formula F = 1/T.

8 Warning Note: Using UPM-28 in Continuous Mode The UPM-28 piezomotor is capable of high force and fast reaction, but it is designed for short duration start /stop applications. Although the motor could be run continuously in continuous mode, prolonged operation in continuous mode can lead to overheating in the motor (unless cooled) and possible internal damage. This restriction does not apply when using the UPM-28 in Stepping Mode. For applications requiring prolonged operation of continuous mode, please contact DTI s Technical Support. 6.0 Technical Support Technical support is available from 9 AM to 5.30 PM U.S. Eastern Time. Please refer to contact information at end of manual. Page 7

9 7.0 Warranty A. DTI warrants to the Buyer that all products and accessories (excluding Consumables and Evaluation Kits) manufactured or supplied by DTI will be free from defects, in material and workmanship in normal use and service from the date of delivery to Buyer as the original purchaser, for a period of one (1) year. Consumables and Evaluation Kits shall have a warranty of 30 days. This warranty does not cover, and no warranty is provided for, parts which by their nature are normally required to be replaced periodically consistent with normal maintenance. If any product covered by this warranty is returned to the original shipping point, transportation charges prepaid, within the applicable warranty period set forth above and upon examination DTI determines to its satisfaction that such product was defective in material or workmanship at the time of delivery to the Buyer, DTI will, at DTI s option, repair or replace the product or the defective part thereof or refund the original purchase price of the product. The foregoing notwithstanding, DTI will not be responsible for damage to any product resulting from misuse, negligence or accident or resulting from repairs, alterations or installation made by any person or firm not duly authorized by DTI in writing. B. If Buyer shall fail to pay when due any portion of the purchase price of any product or any other payment required from Buyer to DTI, whether under the contract or otherwise, all warranties and remedies granted in this Section and all of DTI s warranties and obligations to service, repair, replace, correct or otherwise remedy defects, errors or failures under any other contract between Buyer and DTI may, at DTI s option, be terminated. C. THE WARRANTIES IN THIS SECTION ARE THE ONLY WARRANTIES GIVEN BY DTI WITH RESPECT TO THE PRODUCTS AND THE SOFTWARE PROVIDED WITH THE PRODUCTS AND ARE GIVEN IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ALL WARRANTIES OF MERCHANTABILITY AND OF FITNESS FOR A PARTICULAR PURPOSE. BUYER S EXCLUSIVE REMEDIES AND DTI S SOLE LIABILITY FOR ANY NON-CONFORMITY OR DEFECT IN THE PRODUCTS OR SUCH SOFTWARE WILL BE THOSE EXPRESSED HEREIN. D. An essential purpose of the limited exclusive remedies provided in these terms and conditions is allocation of risks between Buyer and DTI, which allocation of risks is reflected in the purchase price for the products. UNDER NO CIRCUMSTANCES WILL DTI S LIABILITY ARISING OUT OF OR IN CONNECTION WITH THE CONTRACT, DTI S PERFORMANCE OR FAILURE TO PERFORM THERE UNDER, OR THE PERFORMANCE OR FAILURE TO PERFORM OF ANY PRODUCT OR RELATED SOFTWARE, IN CONTRACT, TORT (INCLUDING NEGLIGENCE), OR OTHERWISE, EXCEED THE PURCHASE PRICE OF THE PRODUCT. IN NO EVENT WILL DTI BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL, TORT OR ANALOGOUS DAMAGES, INCLUDING, WITHOUT LIMITATION, DAMAGES RESULTING FROM LOSS OF USE, LOSS OF PROFITS, LOSS OF BUSINESS OR LOSS OF GOODWILL, EVEN IF DTI HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
