Need Help!- 0i-MC Questions

[pmd5700]

We have a GE Fanuc 0i-MC Controller and have a few problems/issues.

1) When transferring files from the Memory Card to the Controller it seems to take a very long time. 120Kb file taking 1 Hour to transfer. Is that normal?

2) Trying to setup transfer via RS-232 cable and the Fadal manual doesn't give a lot of good information on setting this up. We're trying to find information on how to set up the machine for receiving a file from a PC.

Thank You

Not normal. All our 0-I controls will do 1 meg in less than 15 seconds. Check your card, something is not right. Should be a standard compact flash or ATA with adapter.

[pmd5700]

The card is a SanDisk Ultra CompactFlash 30MB/s* 4GB.

Another question/issue is that controller is reporting about 250KB of storage that seems extremely small and I believe the 0i-MC has a 32MB chip. Any ideas?

[underthetire]

No to the 32MB. 250K sounds about right. I THINK max on a 0i-c is 2 Meg.

Find and older card, less than 2 GB. I think it's the Ultra card messing you up.

I'll try to track down a different card, thanks.

As for the memory; according to the Spec sheet for the controller, there is a part A20B-3900-0223 and from what I've found online is a FROM/SRAM 32MB/1MB.

Thanks for your help!

Sounds about right. Fanuc put the 1meg memory in, then charges you extra to change the parameter.

I believe the 32MG was dedicated for operation memory not program storage, but i'm sure one of the better Fanuc option experts will chime in.

Good luck.
BTW try this
Newegg.com - Transcend 1GB Compact Flash (CF) Flash Card Model TS1GCF80

Thanks! I was actually just looking at that card.

I just found out that controllers came with CF cards from Fanuc, they say Fanuc on them and they're 256MB and they still suffer from extremely slow transfer rates.

[pmd5700]

Just bumping this with some new information.

1) Still having slow transfer issues with the memory card. Even using the 256MB card that Fanuc supplied with the controller we get very slow transfer speeds. Could there be a setting somewhere in the parameters or something that is causing this?

2) We're also trying to set up the machine to receive files from a computer. We found something that says.

1 Place the CNC in the EDIT mode.
2 Press the function key PROG .
3 Press the continuous menu key at the right end of the soft key display.
4 Press the [PRGRM] soft key. The program screen appears.
5 Press the [(OPRT)] soft key.
6 Press the continuous menu key at the right end of the soft key display.
7 Press the [READ] soft key.
8 Type the O number of an NC program to be input, with the MDI keys.
[Input format]
<O–number>
9 Press the [EXEC] soft key.
10 During input, “INPUT” blinks in the lower–right corner of the screen.

However, when we press [READ] we get an 086 Alarm. First of all, I want to see if this is the correct way to set up the 0i-MC to receive files from the computer. Second, I looked up the error code, but still can't figure out what it might be.

Thanks in advance for your help!

Alarm 086 is DR SIGNAL OFF, which means either the RS232 cable is not plugged in, or not wired correctly (pins 6, 8, and 20 jumpered on the CNC side), or you have bigger problems.

How is your cable wired? It should be as follows:

DB-25M DB-9F
1 <------ (shield - NC side only)
2 <----------------------> 2
3 <----------------------> 3
7 <----------------------> 5
4, 5 jumpered (NC side only)
6, 8 & 20 jumpered (NC side only)

Thanks for your response. The cables we are using are 25pin on both ends. They were originally being used with Fadal Controllers but we just recently got new CNCs with Fanuc controllers. The cables are custom made. Is that configuration standard to multiple controllers or does each company have their own specific wiring configuration.

The wiring config for Fanuc is all the same. The machine the control is hanging on makes no difference.

The following cable config is for Software handshaking (Xon Xoff) and is the most often used method.

With a DB25 connector both ends the pin out should be as follows:
Machine Side------------------PC Side
1 to shield
2-------------------------------3
3-------------------------------2
4
| bridged
5

7-------------------------------7

6
|
8 all bridged
|
20
