hi,
I am a beginner for EMC2. There are some concepts which are not very clearly explained in the document such like TRAJ_period and Servo_period. I want to increase the sampling frequency in my CNC machine, but I don't know how to change these parameters.
Thank you in advance!

This is in the Integrators Manual.
www.linuxcnc.org/docview/html//config_in...%5BEMCMOT%5D-section
You should run a latency test before changing the base period.
Is your config a Stepconf Wizard generated one? If so after running the latency test you can run Stepconf again and change your latency test number there.

Why do you want to change the period settings?

Thank you for your reply.
Because I want to increase sampling frequency. I don't know the meaning of TRAJ_period exactly.

Other than the information in the first link and in this link that is all I know about traj_period.
