- ~250 cut hours (yes, very low - arguably a bad purchase, but it is nearly paid off)
- Power supplied by Phase Technologies PT030 w/ their surge protection kit (it is my limited understanding that the digital converters are helpful in isolating potential power problems downstream. Spikes, dips, irregularities, etc.)
On Monday the power dipped enough at the beginning of a storm to shut the machine down. The phase converter fired back up effortlessly and has no signs of any problems. It is supplying the same steady voltage across all 3 legs as it always has.
I was just finishing running a few extra parts for the run I was doing and decided to just leave the machine off for the day, knowing I could run a few more the next day or two when I fired it backup for a new setup.
Yesterday I booted up the machine and as soon as I power up/restarted the machine is alarmed out. Alarm 648: DC BUS SHORTAGE
I pulled up the above guide and proceeded to check the regen resistance under "Regen Load"
I assume 4 coils = 4 resistor box.
I measured 5.7-5.8 ohms indicating the regen is not the problem.
I proceeded to check the resistance at the vector drive across t1 and t3 and am seeing .1-.3ohm (short).
Without doing any other testing, HFO is telling me that my drive is faulty/dead. I accept that life sucks sometimes and ask for quote while doing some research on repairs, etc.
HFO will not answer me as to if power outages can/do have the potential to cause this (I understand this may be a hard question to answer black and white, but they ought to know if sudden drops in power can take out a 6k component)
HFO also has not answered if this can be replaced by non-hfo tech and if a usb key is needed to do so. They list the part as needing to be installed by HFO tech on the parts website and cannot be purchased online, must go through HFO. Anyone know?
- Does anyone have the unfortunate experience of having incoming power hiccups take out their vector drives?
- Is it more likely that this drive had an issues and the stars aligned?
- If incoming power problems can have a chance at taking out components, is there anything that can be done, purchased, devised to try to mitigate or eliminate this from happening in the future?
