After setting the parameter, be sure to save the changes and restart the machine, if required.
Keep in mind that incorrect parameter settings can lead to machine malfunction or safety issues. Always consult the FANUC documentation and/or contact a qualified FANUC technician if you're unsure about setting parameters.
