Leo Posted June 30, 2014 Share Posted June 30, 2014 PMAC2 PCI card I want to send 1 position command per millisecond from computer through PCI port. Can this be real ? Link to comment Share on other sites More sharing options...
steve.milici Posted June 30, 2014 Share Posted June 30, 2014 This could be possible. Can you describe your intentions in greater detail? Link to comment Share on other sites More sharing options...
Leo Posted July 1, 2014 Author Share Posted July 1, 2014 This could be possible. Can you describe your intentions in greater detail? I want to built a 6-axis parallel robot with fast response. I hope I can send position command from computer at the speed of 1 command /ms. I chose the turbo PMAC2 PCI. Is that ok or do I need a DPRAM option ? If I choose the CLIPPER board. Is its communication speed ok? Link to comment Share on other sites More sharing options...
steve.milici Posted July 3, 2014 Share Posted July 3, 2014 PMAC’s minimum move time is 1ms. Using a DPR binary rotary buffer PMAC will be able to accept commands this fast – on the PC side it should be possible. The basic requirement is that PMAC must receive a new command before the deceleration begins in the currently executing move otherwise it will come to a stop on that move and not blend into the next received move. This of course will require the DPR option. It will definitely be faster with a PCI bus version of PMAC but a Clipper may not be able to do this as the USB/Ethernet speeds may limit it. I may be able to run a test over USB/Ethernet. Link to comment Share on other sites More sharing options...
