    Mazak 410A alarm 302 atc arm driver malf

    Can anyone tell me how to fix this alarm? We get it when we try a tool change. The magazine will index a tool and it stops and we get this alarm. We get it in the early morning. After running for an hour so the machine warms up and runs fine. Oil levels are good

    thanks, for your help, Mike

    Could you list the full alarm description along with codes mentioned in brackets. Else please check the alarm details in MR-J2 software, or please check the alarm coder on 7-segment display on the drive unit

    Well it turns out the drive was bad. It had a thermal issue that caused it to not work when it was cold. After the machine warmed up we sprayed it with a can of freeze dry and it caused the alarm again. That's how we found it. Took and re soldered all the board connections on the drive and it works fine now.
