Need some guidence with 6t on a Miyano Lathe

[blakemachine]

Ok, I have run Matsuura Mills with yasnac controlls. When you wanna go to MDI mode, you simply turn the dial to MDI, then you can type a line then it insert, and when you are done with the line you hit EOB, or end of line to go to the next line when writing a simple program like homing the machine.

Now with this 6t fanuc controll, when I go to MDI, and I try to type something and then insert, it never inserts it and just stays on the bottom of the screen. Is there a paramater that is not set right? The machine lock is not on as far as I know.

Also, when interfacing with the RS232 port on my matsuura. When I am ready to send a program from my PC to the CNC, I simply go to EDIT mode, then Program Page, then hit IN, and it waits for me to send it from my PC, then I hit send on my PC.

With the fanuc does it work the same way or?

Thanks for your help guys!

MDI Commands:
1.MDI mode
2. Press COMMAND
3. Type M03
4. Press INPUT
5. Type S300
6. Press INPUT
7. Press CYCLE Start or OUTPUT START

RS-232
PC to NC
1. EDIT Mode (program protect must be off to enable editing of programs)
2. Press PROGRAM
3. Press READ (you can type the program number; example O0001; before you press READ
4. EDIT flashes if comms is working

Press PUNCH if you need to send the program.

RS-232 will not work if parameter 2 bit 5 = 0 or if Reader Puncher card is not mounted on the master PCB.

Ok, THANKS!

Ok, I tried to send the program from mastercam, I have the jumpers and send, recive lines correct I belive. When I go to edit, then read, and send the program it errors out and says RS232C code 085. Could it be that the BAUD rate is not set correctly in the paramater page? Does anyone have a list of the baud rates and what parameter line they are on so I can verrify?

Buffer overrun, do you have the S/W set up for XON/XOFF?
Also check the hardware handshake lines, are you using a 3 wire cable?

Ok, it looks like my parameter 311=00101000

Parm340=2
parm341=2

on my setting page TVcheck=0
Punch Code=1
Imput device 1=1
imput device2=1

Does this help figure out our probelm?

Searching I found I have a 6tb controll, and for a 4800 baud I need 311 parm to be 11001001?

if so I cannot seem to edit param 311 how do I scroll over to the right to change it?

[blakemachine]

Also my cable is made like this:

Pins
1= sig ground
2=send
3=recive
4, 5 jumpered

6, 8, 20 jumpered

7=frame ground.

Is this correct?

[Dan Fritz]

Yep. Set parameter 311 to 11001001 Set your DNC software to send at 4800 baud, 1 stop-bit, 7 data bits, Even parity, and Xon/Xoff handshaking.

To change a parameter on the system 6, find the toggle switch labeled "Parameter Write/Enable" on the main circuit board. Turn that switch on, and you'll get an alarm #100 (this is normal). Press the PARAM key and page or cursor to parameter 311. Select MDI mode, press the letter "P", then the entire 8 bits, then press INPUT. Turn off the Parameter write/enable switch, then press RESET to clear the alarm.

Your cable looks OK. There are several configurations that will work with the system 6. You'll definitely need that jumper from pin 6 to pin 8 to pin 20. I like to connect pin 5 from the Fanuc to pin 7 on the PC (the 9-pin plug). This prevents the Fanuc from sending data if the PC isn't ready to receive.

Carefull with your cable:
1 = Frame ground (Connect the shield of the cable here or on the metal housing of the connector body)
7 = Signal ground (The 0V reference around which the signal "swings")

Remeber that:
25pin(PC) 25pin(CNC)
2 < ---------> 3
3 < ---------> 2

9pin (PC) 25pin(CNC)
2 < ----------> 2
3 < ----------> 3


You can also change the Baud rate to 1200 (DC1 to DC4 not required) if you are OK with waiting a little bit longer for the program to transfer.
Handshaking becomes effective for 2400 and higher Baud rates.

For alarm 085 it is important that the parity, character and stop bits also match the host device.

[blakemachine]

Does anyone have a list of the different baud rates, on what to set the parameter 311 to?

I belive my matsuura is setup for 2400 and I would rather keep both machines the same so I dont have to switch mastercam each time I send to a different machine. Plus it is on a 100 foot cable, and I dont know if I can go any faster than 2400 as I might start loosing data during transfers.

Does anyone have a list of the different baud rates, on what to set the parameter 311 to?

Does this help?

Ok, I checked my mastercam sending configurations. Looks like I am at 1200 baud rate, data bits=7 stop bits=2 with a even parity. So what settings on the fanuc controll do I set to to match up with these mastercam settings?

[blakemachine]

Ok, great news!

Got the PC to talk to the CNC. Set parameter 311 to 00100111 for a 1200 baud rate, and works good.

Thanks guys so much!

Ok, now for the newbie Lathe operator help!

Ok, in MDI mode I still cannot input a simple program. HRH says to switch to MDI mode, then press command. That brings me to a whole different page on it. But it still does not let me imput any codes in it.


When I go to start the program that I sent from the PC it errors out after I push cycle start with an alarm 048 "ref rtrn" Any help here?
