[Emc-users] Max speed too fast

Stephen asked: |Is there any particular reason why you chose 2,400,000 for the servo and |traj periods? I'm sure it will work for these speeds (and it does |reduce the CPU load marginally), but it shouldn't be necessary to |lengthen these. Can you share your reason for changing them? Stephen,

Thanks for the help. I set my base period to 15,000, servo period to 60,000 and traj period to 600,000. I lowered my max vel to .75 (45 inches per minute, plenty fast enough). Everything seems happy except the realtime error which I have not run to ground yet. The RT error was there at the

I am using EMC2 and a gecko servo drive to drive a servo I have mounted on my Millrite. When I set the max speed to 1.0 (I think that is 1 ips or 60 ipm) I get an error saying that the velocity is too high. I the motor/encoder/gecko drive require 2000 steps per rev and the lead screw is 5 tpi
