General Mach Discussion / HOMING/SOFT limits

« on: February 20, 2009, 05:59:27 PM »

HI,

I am finishing retrofit with DSPmc controller. Retofit went very smooth although I had no experiences in CNC nor MACH; however Vitalsystems team (Rufi especially and Arto) helped me a lot. Machine is running on AC servo motors with tachogenerators inside for velocity loop in encoders for position loop; an idea is to thank Rufi for very prompt and thural help throughout the retrofit.

Mine last questions are about homing/soft limits. I use shared swithes for homing and soft lim and I did set up mach as seen in help (see http://picasaweb.google.com/bostjan681/Homing?feat=directlink);
When I go in homing sequence stops when Z switch gets hit saying soft limit triggered. Is there any more elegant solution as swithing off soft limits each time when going in homing?
This is probably DSP question but I can try

General Mach Discussion / No back move at homing

HI,

while homing movement hits switch, zeroes, but it does not move back to release the switch.

Where do I have a problem

I have DSPmc controller

General Mach Discussion / refitting AC SERVO SYSTEM TO MACH

« on: August 08, 2008, 05:06:57 AM »

HI MACH team;

I would like to swith from home written controller (SW) to mach. Machine is AC SERVO driven with encoders (see photo)
Drivers are analog, all from INDRAMAT. System work in closed loop, all works very good but does not satisfy my milling needs!
I would like to change only the interface from MACH (PWM and direction) to analog (+/- 10 V) input to drivers. Since I a not sure o that help me with some tips how to appoach the project, what to buy...
