Hi people,
I am new as a member but not as a gawker. I have found useful information here in the past and I hope that I can both help and be helped.
I have a mazak 640t/ qt350 servo error 3b on controller mds-b-sp-300. The manual doesn't cover this alarm. Front panel alarm code is 021 (1, ,&003b). The mazak rep. says this alarm is caused by overheating.
Told me to check the rear fan for freedom of movement and dirt, clean if needed. This was in case of intermittent operation under this code.
After informing him that my problem was not intermittent but constant. He informed me that that controller needs replacing.
If any one is getting this alarm intermittently. Remove your servo and clean it.
Now, I am looking for a mds-b-sp-300 controller under $1700USD way under. my budget is $700USD. new, used or repaired.
Any suggestions as to alternative causes or repair solutions welcomed.
Sadly, after all these years and easily avoidable equipment failures. Preventative maintenance and lack of communication / documention of intermittent problems continue to be the number 1 cause of equipment downtime due to breakdowns.
Even if your company won't take action, record the problems. You know, squeaky wheels even if sounding annoying, puts you on notice that there is a problem.
