Ernst.Q Posted August 16, 2013 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.
steve.milici Posted August 16, 2013 Posted August 16, 2013 Yes - you can use these for the extra encoders.
Highland Controls Posted August 19, 2013 Posted August 19, 2013 As long as you are not using closed-loop steppers.
curtwilson Posted August 19, 2013 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 Posted August 19, 2013 Sorry, I missed the "drive" part of that and was thinking it was a standard Clipper.
