Ernst.Q Posted August 16, 2013 Share Posted August 16, 2013 For an OEM application, I have need of a controller/drive for four axes. Two axes are dual loop, so I need 6 feedback channels. The Clipper Drive seems a suitable solution, but standard only has four encoder channels. As two feedback channels are velocity only, I will not need index on those. Is it possible to use the handwheel encoders as a secondary feedback? If not, what other options do you suggest. Link to comment Share on other sites More sharing options...
steve.milici Posted August 16, 2013 Share Posted August 16, 2013 Yes - you can use these for the extra encoders. Link to comment Share on other sites More sharing options...
Highland Controls Posted August 19, 2013 Share Posted August 19, 2013 As long as you are not using closed-loop steppers. Link to comment Share on other sites More sharing options...
curtwilson Posted August 19, 2013 Share Posted August 19, 2013 HC - I'm not following why closed-loop steppers would be different. The Clipper drive controls stepper motors in "direct microstepping" mode, not using pulse-and-direction control. In P&D control, we often feed the output signal back to the encoder counter in open-loop mode, but this does not occur in direct microstepping.

Highland Controls Posted August 19, 2013 Share Posted August 19, 2013 Sorry, I missed the "drive" part of that and was thinking it was a standard Clipper. Link to comment Share on other sites More sharing options...
