When I do PID tuning I usually skip EMC completely. I just set up a simple single axis HAL configuration using "siggen" as the signal source. Run the siggen square wave output through a "limit3" block and you get a classic trapezoidal velocity profile of whatever length and repetition rate you want. Then I use "setp" commands from the halcmd command line to tune. Once I have values I like, "show param pid" displays them, I jot them down, and enter them into the ini file or wherever they are needed.
