Mazak M32 #8 Battery alarm.

[ScottAMT]

I'm having problems with a Mazak H-500 mill. I'm getting a alarm # 8 battery alarm. I've checked voltages on the 3 batteries I could find. the 6 volt battery is at about 5.7Volts. I found 2 other batteries on the nc control and both have good voltage.
Are there any other batteries I'm missing.
If not what can cause this alarm. It won't allow the machine to move at all with this alarm.
The machine has sat about a week waiting for the y-axis drive to be repaired. I replaced the drive and turned it on. That's when the alarm appeared.
Any help would be Appreciated,
Thanks!!

I have had similar issues with my Nexus 410 and 200B. There are batteries that support the tool mag. I was told by Mazak service they are only good for about 1- 1-1/2 years. We go to a local BatteriesPlus and take them the battery, they unsolder the wire and connector and re-solder onto a new battery, cheaper than Mazak. On mine we always replace them in pairs. When I get to my shop, I will see if I can take a picture of where it is located and post on here. Seems like they are on the tool mag drive in the control cabinet behind a little "flip down cover".

There should be a motorcycle style battery in your electrical. It should be around 6v but I'm not sure at what voltage it will alarm out at.

Onboard batteries on 442, 471 or 472 or 474 if so equipped. 3.6 Coin cell in O62 battery box under the 721 drive.I think you should have three 3.6 coin cells and the 6 volt sealed lead acid total.
