gmschoon Posted October 12, 2018 Posted October 12, 2018 In the ACC24E3 user manual, page 100 suggests that ALTCOS & SIN can be read via Gate3.Chan[j].AdcEnc[2] & [3], with no automatic calculations performed, however page 52 & 53 suggest that the closest (of 8 options) we can get is to have raw A/D data for SIN/COS by leaving Gate3.AdcEncStrobe as default or "&" to clear. Given that we want to have ALT COS & SIN signals in Gate3.Chan[j].AdcEnc[2] & [3] registers, which section in the manual is correct? Thanks for any feedback
curtwilson Posted October 15, 2018 Posted October 15, 2018 Both sections of the manual are correct FOR THE PARTICULAR HARDWARE INTERFACE THEY DESCRIBE. If you have the resolver interface board installed on the ACC-24E3, the ALTSIN and ALTCOS input values will be found in AdcEnc[2] and [3]. If you have the auto-correcting interpolator board for sinusoidal encoders installed on the ACC-24E3, you can get the raw SIN and COS values (unfiltered and uncorrected) in AdcEnc[2] and [3].
