MRJ2 Problem

Hello Everyone,

I've got a tough one and I'm hoping someone can.

I am working on a Mazak Hyper Quadrex 150MSY with a Matrix control. The machine was powered off for more than 6 months and when power was finally restored, the batteries for both MRJ2 turret drives (this is a twin spindle, twin turret lathe) had died. With power restored, the following alarms were displayed:

Battery Alarm (Turrets 1 and 2)
Detector Malfunction (Turrets 1 and 2)
Emergency Stop (Turrets 1 and 2)

Once the batteries in the drives were replaced the battery alarms went away, however, the Detector Malfunction and Emergency Stop alarms are still present. I assumed that the Absolute Position had been lost in both turrets due to the dead batteries. I went into the MRJ2 software and sure enough, the alarm tab in both turret drives confirmed this so I hit the soft key and re-set Absolute Position in both turrets. I then powered down the control and powered off the main breaker, flipped on the main breaker and powered it off again as described in the maintenance manual. The main breaker was then turned back on and I powered on the control. Unfortunately, the alarms did not go away. I experimented with several variations of this procedure to no avail.

I can confirm that the parameters are present in both drives and as far as I can tell, all of the communication cables are in their correct locations and plugged in firmly. I also dug back into the old alarm history on the machine and can confirm that the Detector Malfunction and corresponding Emergency Stop alarms were not present when the machine was powered down months ago.

I'm stumped. Any suggestions?

Thanks,
Gary
