dzrong Posted January 18, 2013 Share Posted January 18, 2013 Hello Everyone: What's a good idear to caculate the time for SPLINE2? Especially for limitting the max velocity or max acceleration,like the lookahead do. Thanks Link to comment Share on other sites More sharing options...
steve.milici Posted January 21, 2013 Share Posted January 21, 2013 Turbo PMAC uses "way-points" to calculate the velocities in SPLINEx mode. Check the Turbo PMAC User’s manual under the SPLINE section for these details. Link to comment Share on other sites More sharing options...
dzrong Posted January 29, 2013 Author Share Posted January 29, 2013 Hello Steve, The "way-points" is used for SPLINE1,is there a formula for SPLINE2 to calculate the "way-points"? Thanks Link to comment Share on other sites More sharing options...
steve.milici Posted February 5, 2013 Share Posted February 5, 2013 Our SPLINE2 may be considered proprietary - I will look into these details and if I can post the math. Link to comment Share on other sites More sharing options...
Dan1223 Posted February 5, 2013 Share Posted February 5, 2013 Would the movetime command provide the calculation you are looking for? I have used this for simple linear moves but I haven't tried using it with a spline move. Link to comment Share on other sites More sharing options...
dzrong Posted February 6, 2013 Author Share Posted February 6, 2013 Because my customer want to go through a serail points in his machine,if using LINEAR with LOOKAHEAD,the "way-points" maybe not the desired POINT,because don't hope stop at any where and Blend is open and the speed should be as fast as possible. Like the LineartoPVT in Power PMAC. Link to comment Share on other sites More sharing options...
