JeffLowe Posted November 19, 2014 Share Posted November 19, 2014 What documentation exists for the autocorrecting interpolator? Is it simply a plug and play, or is there more? Also, How does the input bandwidth compare to that of the ACC24e3? Link to comment Share on other sites More sharing options...

steve.milici Posted November 20, 2014 Share Posted November 20, 2014 This is documented in the "Power PMAC Users Manual" under the section "Setting Up Analog Sinusoidal Encoders" starting on page 102. Link to comment Share on other sites More sharing options...

curtwilson Posted November 20, 2014 Share Posted November 20, 2014 Because anti-noise filtering in the auto-correcting interpolator is performed by extreme oversampling and digital averaging, the analog filtering on the front end is a lot lighter. This means that the input bandwidth is a lot higher - high enough that we do not have a sinusoidal encoder that can exceed its capabilities.

Omron Forums Support Posted November 21, 2014 Share Posted November 21, 2014 It's very simple to set up, so yes, basically plug and play. Just follow the recommended Encoder Conversion Table entry in the manual and set up Gate3.AdcEncCtrl for normal use (Gate3.AdcEncCtrl = $80000000), which is basically auto-correction with zero header bits (required), no unsigned-to-signed conversion (required), and no strobe/latch delay (acceptable for most applications).
