Hi Guys,
Hope this is on the correct forum.
We have a Tormach 1100 and recently, for no apparent reason, it has been critically malfunctioning.
These are the symptoms:
- The software executes 'circular interpolations' as if in 'incremental mode' instead of 'absolute mode' resulting in wide arcs seemingly at random.
- The Machine halts and powers down erroneously after the 500th line of code of any .tap machining file. At this fatal point the spindle turns-off and the machine audibly fades, with no axial movement.
It appears the fault is in the The VFD motor driver board (30163, (with ref to drawing D40135 electrical overview), as when symptoms occur machining ends abruptly, followed by the board's red 'Fault' LED winking on and off.
If anyone has any ideas we would love to hear them. We have tried reformatting and even completely changing the computer that runs the Tormach to no avail, so this is most likely a Hardware issue with the Tormach itself.
Thanks!
Dan
