|
| By: Tom | Posted on: Feb 14 2006 at 06:09:10 PM | The machine with Fanuc 15M control ,I used feed mode, it run about 15 min then i get alarm : Buffer over flow....
even i set block delay to 9
Please help...
Thanks | |

| By: Guest | Posted on: Feb 22 2006 at 06:03:44 PM | If i want to check Parameter of the control, which one i have to look at?
Thanks | |
| By: Support | Posted on: Feb 22 2006 at 07:11:06 PM | The data speed settings are parameters 5112, 5122 and 5132. Setting those to a value of 9 changes the datarate to 2400.
Let me know what the following settings are
5001
5002
5003
5110
5111
5120
5121
5130
5131
Something else. This error you say happens after 15 minutes. Is it always exactly the same place in the process ?
Is the computer COM port a proper onboard port or is it a USB adapter? | |
| By: Tom | Posted on: Feb 23 2006 at 03:32:30 AM | I machine part with 3D surfacing, If i run the feed rate fast about 250 IPM i have no problem, soon as i slowed down to 150 IPM or slower then the alarm comes up after 10 or 15 min.
The alarm comes out at different spot.
Thanks for your help. | |

The data is being fed block wise into the machine and the computer would normally be able to send data faster than the machine can process it so flow control is used to make the computer stop every so often allowing the machining process to catch up.
During these pauses you`ll see on the computer screen a little info window appear saying somthing like "Waiting for CNC".
When running at a slow feed rate do you see that info window appear? Does it appear when you`re running at the fast feed rate as well?
What flow control setting are you using ? | |
| By: Tom | Posted on: Feb 24 2006 at 06:00:24 PM | I will check baudary on Fanuc control tonight
Yes, i see the note " Waiting for CNC"
I set flow control: Xon/Xoff wait
Thanks | |
| By: TOM | Posted on: Feb 28 2006 at 04:23:05 PM | The parameter set on my machine are:
5001 1
5002 3
5003 0
5110 1
5111 2
5112 11
5120 1
5121 2
5122 11
5130 1
5131 2
5132 10
Please give me an advice.
Thanks | |

Make a note of your current settings so that you can go back to them after this test. Then change them as follows.
5001 = 1
5002 = 2
5003 = 3
5110 = 4
5111 = 2
5112 = 9
5120 = 4
5121 = 2
5122 = 9
5130 = 4
5131 = 2
5132 = 9
There`s a setting labeled "TV Check". Just look to see that`s set to 0
At easy DNC setup change the speed/baud rate to 2400.
Let me know how that goes. | |

Yes, you are right. After i corrected the baundary in control. The software works very smoothly. Untill now no problem at all.
Thank you for your supported.
Refer to any one who looking for a DNC software.
