Actual Position Value fluctuating-Acc84E

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

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.

Hello Eric,

Thanks for the reply.
