Meltdown, while I look for an appropriate power supply, can you help me understand the mail sent to me by Kondo guys with regards to servo vibrations? <br />Here is the mail, along with my request for clarification: <br /><br />Mail from Japan say: <br /><br />&gt;Overshoot means to control to converge the degree of motor axis as you know. <br />&gt;Please adjust the overshoot damping parameter. <br />&gt;In general, servo motor controls the motor using PD <br />control. <br />&gt;Overshoot is adjusted by P and D parameter in the kondo servo motor. <br />&gt;If P parameter and D parameter are mismatch, the <br />motor shows <br />vibration. <br /><br />************MY QUESTIONS*********** <br /><br />Could you please provide me with further details? <br /><br />- Does P stand for pulse stretch, and D for deadbandwidth? <br />- If yes, In SERVOMANAGER program there are 5 radio buttons for each of the abovementioned parameters. <br /><br />I understand I have to assign the same values to both pulse stretch and deadbandwidth. Is it correct? <br />Could you tell me which one, among these 5 radio buttons, do I have to select? <br />Furthermore, with regard to the pulse stretch specifically, on which pulse stretch set (1, 2 or 3) do I have to select the radio button? <br />Do I have to define this "radio button" value for all three pulse stretch sets? <br /><br />And for each pulse stretch set to be defined, which speed value (1,2,3) do I have to assign? <br /><br />Do you know how to solve this? <br /><br />By the way, you said you use a 6V &amp; 7A power supply which is definitely fine. <br />I saw on this website that a 6V &amp; 12A supplier - recommended by Kondo - has been added to the catalogue. <br />Do you know what is the difference between the two? <br />What are the impacts of using a 12A supplier on Kondo? <br /><br />Thank you for your valuable advice, <br />Regards, <br />Ninja<p>Statistics: Posted by <a href="http://forum.robosavvy.com/memberlist.php?mode=viewprofile&amp;u=54">ninja</a> — Sun Dec 11, 2005 11:40 pm</p><hr />
