Need Help!- Alarm 110 on Power Mate Model D/H

[AZDEN]

Hi All,

This alarm is a Data Overflow alarm - The absolute value of fixed decimal point display data exceeds the allowable range. Modify the program.

The largest decimal displayed in the program is 5 places and is the same line of code from a program that runs on this machine daily. The only difference between the programs, is the every day programs use variable calculations for axis movement after G codes. The new program uses actual position dimensions. ( G01X[#501+#134] vs. G01 X2.1 F1.0)

The program start looks like this-

%
O420

G18G20G90G94
G92X#2005Z#2006

This equipment is a custom OD Grinder. Is it possible that I'm confusing it by using the G94 and a feed rate in IPM?

My manual says G94 is feed per rev. in the g code list, but in the feed function portion of the manual it says G94=feed per minute.

If anyone can help I'd appreciate it.

Thanks in advance

I think the G-Code list is wrong. G94 should be IPM, G95 should be IPR. Used to be IPM feedrates use a different format, i.e.: f4.1 than IPR feedrates, i.e.: f1.4, but I don't find that in the book. What are you programming for F?

[AZDEN]

I'm programming simple G01 moves.

Here is the entire program.

Where does the alarm occur?

[AZDEN]

when cycle start is pushed

[dcoupar]

Yeah, I kinda figured that. Being that I'm not familiar with the Powermate D/H, these may seem like stupid questions to you, but...

When the alarm occurs, I presume that an ALARM page is displayed? If so, can you go back to the PROG function and see what block the alarm occurred in? Or, have you tried it in Single Block?

[AZDEN]

The alarm happens at this block

#100=3.865

The alarm display just flashes and goes blank, but I can go to the history page and see the alarm message

[dcoupar]

My guess is it's one of the 2 blocks after the alarm.
#500=[[#2001/2]-#2002]
#505=#505+1(DRESS COUNT)

Well, I don't see anything obvious, but I'm not a macro whiz. Two thoughts, though;

Does #2001 (Tool offset 1?) contain a value?
Maybe add #500=0 before these 2 blocks?

[AZDEN]

#500 calculates the wheel diameter.
I removed the#505 line and got the same result.
