The primary axis motor makes weird noise after or while coming to stop. It does for half a minute and then its quiet. The time for noise vary though. Below is the program uploaded on the primary motor axis. The secondary motor is uploaded with a program to go to postilion in relative to motor 1. Thanks in advance.

What is the full PN of your motor?

I would guess that it is related to your tuning parameters. Are the default values not sufficient for your application? How did you determine the above values were correct?
Did you restart it?

Also, please look at the X command and consider using this in place of the S command.
