Adjusting ACC/DEC on a A2100

[Rob_N]

I am looking through the programming manual and I cannot seem to find the page listed on the control that controls ACC/DEC.

We are supposed to have the high speed die/mold package, but I really do not know exactly what thats supposed to do. ACC/DEC is on by default G45 and I can turn it off with G46, but Off is too drastic. It bangs to hard at higher rates

The manual states options like G54.1 for Roughing profile, and G54.01 -G54.03 for Programmable settings. These do not seem to work, (unrecognized g-code) so it must be yet another "paid for" option.

I rough with Dijet SKS High feed roughers at around 220IPM with .04-.06 DOC depending on the type of steel, for CRS 220ipm is normal, for Zinc or Aluminum I approach 400ipm. With the A2100 on an Arrow2000 it is stopping or slowing down way to much in the corners, A 45 minute roughing program takes 2+ hours to complete. The same program on our Takumi with a Fanuc 18m control using HPCC (G5P1000 command) is takes just under an hour to complete. It does not stop so much in the corners.

It was not always this way, the last time we had a HDD failure I think something did not get turned back on or setup correctly, but sadly the company the did the replacement is no longer around. I hope to adjust/fix this myself and a call to MAG or whoever is serviceing these now would probably be expensive

I know you can adjust the parameters for acc/dec and i've typically done it during any setup I've performed since they come set up shall we say piss poor from the factory. (I was a Tree distributor AE for a number of years.) Amazingly they are not protected so you can mess with them at will. Program a 4x4 square with a fast feedrate and then adjust the parameters and try again. when they are adjusted right, your machine will corner smooth as silk.

I'm a bit rusty on these since I did this in the late 90's, but may have some more info around here if you have trouble finding the system parameter.

Thanks for the reply, currently the machine is a huge paperweight as the control pendant is dead.

Poor design I think, that you cannot use the machine when that thing dies...

No money to replace it at this time and we are pretty dead, so It'll wait until things pickup before we get someone in to fix it.

See this.

I authored this many years ago with the help of a very talented servo engineer. The screen shots may not match yours due to S/W version changes.

Good Luck,
