Anyone have experience (or know of a thread) with the best method to use the acceleration options on the servo driver itself when using Mach2?
I am using Emerson servo drives with step/direction inputs from Mach2. Currently it is setup as 2048 pulses per rev on the servo driver and I have some arbitrary acceleration constant input into the servo driver itself. As I understand it, it will move each 'step' with an acceleration and deceleration.
So If I put an infinite accelleration on the servo driver, then it will try to 'step' as fast as it can every time Mach tells it to step. ( I am not home now and cannot try things so I figured I would ask here) Mach will ramp up the stepping, but the driver is going to do all it can to get each step completed ASAP. I would be afraid that it will be too aggressive and cause excess heating.
I plan on upgrading to Mach3 and then increasing the pulse rate and change the pulse per rev to 4096 or 8192 which would make jumps smaller and maybe smoother. But if the servo driver circuit is fast enough it may have same issue.
Any thoughts or experience with this would be appreciated.
Thanks!
