It's 20 year-old stuff - Windows 98 era - so maybe I need a time machine so I can go back to when I could get tech support from IAI.
Yup - checked the check box next to 'Parameters' when the point file showed up 'corrupted' (all 3rd axis points had reverted to 'xx.xxx') and I thought I'd just start from scratch - clear memory and reload from PC.
The backup parameter file was on a floppy that apparently had degraded.
It is having encoder errors with the default values - don't know if the defaults are 'proper'.
IAI is not letting go of their techncal documents - just stupid user manuals.
I need something that explains why my 'motor pulses' option is either 800 or 400 - and what it should be - as well as the meaning behind all the other servo parameters. Just a look at someones' similar parameters would let me know what parameters might be better if changed.
Controller is SEL-G-3-AC-100C.100C.60C
BTW - if someone would like the Sel-Win program - I can share.
For your amusement - a picture of my 3-axis project...
I NEED HELP! Parameter file (*.prm) wanted for old IAI Sel-G controller.

Hi Bithead! Can you please post the model of axis connected to sel controller, (the sel controller show any error code)?
Regards!

Actuators are...
IS-M-X-M-10-100-700C, IS-M-Y-S-10-100-500C and the z-axis with a worn-off label I'm guessing might be IS-M-Z-S-4-60-100C.Error codes? Yes - all the time. Well, actually, the A2 that it had on first power-up has gone away since I took the controller apart - replaced battery.
Now it gets A3's and A4's.
Update - I have'nt seen an A4 since I took the controller all apart, put the circuit boards under a microscope, went around the IC's - wiggling pins with a tweezers, had a few 'snap loose' from their pads - and resoldered them.Now the actuators move smoothly using the 'Test Mode' window - and when I changed the default 8mm/rev for the Z-axis to 4mm/rev it scaled properly - which is why I think the '4' in the model number is correct.
I saved that parameter file.
However - homing is now an issue.
Upon hitting the HOME button, they all do a nice smooth move about 5mm, stop and call that 'home' - setting current position to 0.00.
Changing the 'HOME' direction in the parameter file changes the meaning of 'Forward' and Backward' in the Test Mode window - which is proper.
But, it has no effect on the direction it goes with the 'Home' command - always moves CW (or is it CCW?) - towards the motor.
It has had homing issues before but I think it was related to limit switch 'yes/no/24V power' things.
Homing used to at least head the slides off to the end of travel.
Hm-m-m-m... maybe it is a limit switch thing after all - like it IS at a limit and is doing a 5mm 'backup' to a 'Z-pulse' ?
BUT - why not change direction with 'Home Direction' changes in the paramter file?
I need technical docs that describe what Z-pulse and limit switch parameters mean.
I need to find someone who had 10 years of experience with this thing 10 years ago.Oh - yes, they all have limit switches and the z-axis has a brake.
