I tried these values on one of my machine, and they work..( Mill) but you may have to reduce the sps a little if the servos fault on G00.
Acceleration Tab ( Machine set up)
acceleration = 4500000
accel scale = 30
Max Velocity = 45000
start velocity = 1500
This will give you 2700 rpm max, you can up it, but I have found that getting to the upper rpm limits will fault the servos, depending on the machine dynamics.
The time of accel with this set up is .286, and unless you have a real heavy machine ,should be enough. ( untill you change the Max velocity (sps) in the axis set up page you will get a warning "Max Velocities do not match "
AXIS SET UP PAGE
change the the Max velocity (sps) to 45000 on all axis used.(See comments below)
I assume from your math that you have figued the steps per inch ok ?
You can also do a "custom Accel graph" by going to set up, and the last one listed is "modify accel graph"..I'm sure after you look at it, you will be able to configure a graph the fits your machine.Takes awhile, but I changed mine for the Lathe project, made it real smooth.
After you get past the accel stuff, the system works real good..I dinked with the values 2 days before understanding what was needed on the 1st machine.
You can raise or lower the velocities as needed by the machine...The machine dynamics are all different, so to have an absolute number will not work.Typically, you would want to slow the Z axis way down as they usually are kinda short..just change the max vel(sps) in the axis set up page., Certinly the Y axis would react different than the longer ? X axis, so it might take some time to make your machine work right for you.
