Boss 6 Problem ??

[DaveinUK]

We have not used the Boss 6 for a while, possibly 4 wks or more.
This morning when I switched it on all seemed fine until I went to move it in the X axis, it moved then stopped in all three axis.

I have shut the machine off, then started it again but the same happens, it
will move for a few seconds in any axis then stop.

I have checked the transistors on the X,Y,Z axis and they are all fine.

I have tried the reset/clear switch, checked all the fuses, and the level in the lubrication bowl all seem OK.

Could it be the control panel ??

Any Idea's

Any LEDs lighting up? Like GOTO or ERR?
Logic supply OK?
Are display numbers moving (reflecting where the axis should be)?

Hello George,

Yes all the LED's on on and there is no GOTO or ERR showing.

I can't get the axis to move at all today.

I'm going to check the transistors on all three axis again today, just in case I missed something.

Thank you for you help.

I've now checked the transistors again in all three axis, there are no faults.

The display numbers did move when the axis moved.

I don't know how to check the logic supply. Is this when you use the
reset / clear switch

If the numbers are moving then the logics are OK and your problem is in the drive section. If all 3 are dead then the common areas are the 54V power supply, the ACC board (even though there are 3 distinct sections to it), and the ZDI (but again 3 opto-couplers out for each axis) which sends the commands to the SMD boards. May be that 54V power supply.
There is a trouble shooting section in the maintenance manual with step by step where to find each voltage.

George

I will let you know how I get on.

Thank you for taking the time to reply.

Hello George,

How do I check the 56v power supply. I do have a multi-meter.

What happens to the display #'s when the axis stopped moving? Do they continue to count?

Hello Darek,

I can't get any of the axis to move today.

The control panel seems OK all LEDs on with no error messages.

I have asked, how to check the 56V power supply.

Dave,

You can check the 56V power supply at FU10 to ground with a volt meter.

Do you hear the drives reset when you hit LIMIT OVERRIDE (limit light should go out also)?

I believe there is a fuse on the left side of the terminal strip where fuses 12, 13, and 14 are. I do not remember if it protects the AC or DC side. I am on vacation (holiday on that side of the pond) and do not have that data with me. The maintenance manual should tell you.

Thank you both,

I will check it out.

Does anybody have a wiring diagram out there.
