Figured I would ask on here before I call up Hexagon and ask for assistance. So This new company I'm working with has bought a brand new off the shelf 7-10-7 global EPS (aka, Brown&Sharpe) top speed parameters shows 300. This thing is slower at top speed then this old Mistral, I used to run. I would think this thing should go a lot faster. At one facility here, I have a 5-7-5 global EPS top speed 500. I would like to believe that this thing should move, so before I go changing any numbers. I would like to know if this is the best this thing can do or is there a setting that can make this thing move. Calling out

Rondog, or anybody else that may know the answer.
Not an option on the Sharpe32 under machine interface setup, the Global has it and they are set to 500. I would guess that if those values are set to 250 (even if they could be higher) and you put a move speed of 500 in the program, it will only do the 250.
Yeah what
mckenzie said or before you open a program. Under Edit/Machine Interface Setup. And Yeah I know the check box item. Now that Hexagon has made this default, being a % guy I have had to uncheck this box. since what?, 2016 version? because before I could go into Settings editor and change it there. It don't work anymore. But Yeah, I'll try this and crank it up. I have a bad feeling this thing is set to as fast as it will go. Which is really sad.
if 300 is the max (and that machine isn't in the list I posted), try cranking up the ACCL values. Those are what will really give it the speed. If 300 is the max, but you are using the default ACCL values (which I think are 200?) then it takes forever to get up to speed and forever to slow down. As far as I know, if the controller is limited to 300, then 300 is as fast as it will go, even if you tell it 500, but crank that accl value should give you are surprise.
When we got our new machines a few years ago I had the same issues. I was told by the service who did the cal was that the classic & performance were the exact same machines as the ADVANTAGE but with smaller drive motors. Now that may be a little over simplification but he then said, yeah you got the V6 because they didn't want to spend the extra for the V8 upgrade.
I hate the % stuff. We have one guy here that programs everything at 80% so when the program goes to DCC, It takes off and gives me a good scare. I am constantly changing them to absolute.
Most of the Globals are locked out internally on speed. So even if you type max accel to 50,0000 it'll only move to it's internal speed setting. Same with the movespeed command being set to very high it'll still move to what it's locked at like in your case.
Assuming it's locked.
Use the command I listed above and put 5K in there along with absolute speeds set at 500. Create a safe move point and test....don't crash!
Ok folks, I did call Hex, based off of the motor on this particular machine and controller. Top speed for it is 300. I did attempt putting larger speed numbers in there. And this machine would just error out not move at all.
Matthew D. Hoedeman did try the absolute speed, ran no different then 100%. So I can continue to do it the correct way and run it in %.
