Hello all,
I've changed over our wire EDM from .010" wire to .004" wire, and during the wire guide alignment process, I receive error messages E67 "Cycle Aborted" and E68 "Out of Tolerance". The info page for resolving these issues basically says 'hit reset and run it again', but the same error messages come up again and again.
P/S ALARM
ALARM 67
The edging (G70), hole centering (G71), slit centering (G72), or wire guides adjustment (G73) was interrupted by the following:
1. FEED HOLD (I don't know what this is)
2. Wire breakage (wire isn't broken)
3. Measure cycle starting with short-circuit (I started in the center of the guide adjustment tool)
4. Change of operation mode (?)
5. Alarm other than P/S (this says it is a P/S alarm at the top of the page, so, no)
6. No establishment of the reference position (guide adjustment page has no requirement for a reference position [if they mean the center of the guide adjustment tool {the ZB height}, then that IS established on that page])
Press RESET, then execute the measure cycle again.
P/S ALARM
ALARM 68
The error of the detection point exceeded the tolerance in the measure cycle. (Yesterday the tolerance was set for .00198". When it failed this morning, I upped the tolerance to .005" and it still failed. Being that this is .004" wire, the product is required to be VERY accurate- I'm not sure what increasing the tolerance will give me for a quality product.)
Response:
Press RESET, then execute the measure cycle again.
Any advice?
Thanks,
Ash
Follow up- Instead of aborting the cycle in the middle of moving the U and V axes, it then started to abort only while establishing the X and Y axes. Then, it would abort when the Z raised up to begin the guide alignment. I restarted the machine (when in doubt, turn it off then on again, right?) and it continues to abort the cycle when the Z raises up to begin alignment.
