beheredurgesh Posted June 20, 2019 Share Posted June 20, 2019 Hello, We are facing a problem with the actual position value with the below configuration. We are interfacing absolute SSI 22 bit encoder with PPMAC 465 CPU using ACC-84E. We have the following configuration Acc84E[14].SerialEncCtrl=$633102 Acc84E[14].Chan[0].SerialEncCmd=$1c16 Sys.ServoPeriod=0.25 Sys.PhaseOverServoPeriod=1 We can read the value but the actual position value is fluctuating. Do you know the expected settings to make the reading stable? Regards, Durgesh Link to comment Share on other sites More sharing options...
Omron Forums Support Posted June 21, 2019 Share Posted June 21, 2019 Can you be more specific? Is the position rolling over? Please check Motor[1].pEnc (or replace the 1 with your motor number. Your response should be like Motor[1].pEnc=EncTable[x].a where x is enctable number Issue "backup Enctable[x]." in the terminal. No quotes, but you'll have to his escape to get rid of the intellisense suggestion. Copy the Enctable[x] settings into a reply. Link to comment Share on other sites More sharing options...

I have executed commands suggested by you. I am attaching the image of the output of the command. Thanks. Link to comment Share on other sites More sharing options...
Omron Forums Support Posted June 27, 2019 Share Posted June 27, 2019 If you put Acc84E[1].Chan[1].SerialEncDataA (important to leave off the .a) in the watch window, do you also see fluctuations? Link to comment Share on other sites More sharing options...
