I'm hoping someone out there can help. I have a motion problem with my machine and am trying to set parameters so I can see the actual spindle RPM to determine the problem, I'm also trying to turn off the spindle speed check bit to get around the ppoblem. Using the book as a reference I am turning on the parameter set mode. I then change the parameters and as the manual instructs I am turning off the power. After powering up I turn off the parameter change bit and the parameters appear to have been changed but do not actually change any function of the machine. Our service guy ran into the same problem trying to adjust for backlash. Kitamura has not been able to help and Yaskawa who now takes care of Yasnac service has not been able to help. Any input would be appreciated.
