Hi All,

We have milltronics rh-30 with centurion 6 controller, and we want to transfer larger program in dnc mode with rs-232 cable, we made cable and setting same as milltronics service says, and we use nc link program as sender, but when we click to send from to pc then F10-UTIL, F6-DNC, F3 FAST then RS-232 but machine show on the screen WAITING FOR DNC LINK, all of thing is look like ok but what is the problem why we can not use that? anyone has any idea to help me??

Also same machine has 7,5 KW yaskawa motor and VS-626 M5 yaskawa inverter,
Our problem is spindle does not has any power to cut soft material or drill small hole, spindle is stopping while we cut the cast material nearly 0,5 mm and after this we need to shut down the cnc and then open again, in fact we dont understand why our machine spindle is not powerful, ı think so its because of parameter, or another ? please help me if anyone has any idea,,


Thank you......

This might help with the RS232 issue:


RS232 COMMUNICATIONS
Cabling, Connections, and Configuring


To connect the communications port on the milling machine (COM1) to the communications port on the PC (COM1 or COM2):

Centurion SLS Software Control
1. Set the parameters on the milling machine control.
from the MAIN MENU, press F7 UTIL, F8 PARAMS, F9 CTRL

2. Use the arrow keys to get down the list to change/verify the parameters. (use the F3 key to toggle between the options.)

Primary Serial Port is ....................COM1
COM1 Baud Rate = .....................19200
COM1 Parity; Data and Stop Bits ...E/7/2
Secondary Serial Port is ................NONE

Centurion CNC Software Control
1. Set the parameters on the milling machine control.
from the MAIN MENU, press F7 PARAMS, F9 CTRL

2. Use the arrow keys to get down the list to change/verify the parameters. (use the F3 key to toggle between the options.)

Primary Serial Port is ....................COM1
COM1 Baud Rate = .....................19200
COM1 Parity; Data and Stop Bits ...E/7/2
Secondary Serial Port is ................NONE

PC Computer
Note: the computer may have more than one Serial Port. Other devices that use COM ports include Printers, Plotters, Mice, and Modems. More than one device trying to use the same COM port may cause communication conflicts. Additional ports may need to be added or switch boxes may have to be installed in order to connect all devices.

1. Identify the Serial Port(s) at the back of the computer. There are two types generally found - the DB9 and the DB25 connectors. These will be male connectors with the pins sticking out.

2. On the DB9 connector, take a voltage reading between pin #2 and pin #5 (receive pair) and between pin #3 and pin #5 (transmit pair) - the Receive pair will read some odd voltage, the Transmit pair will read approximately 12 volts DC.

3. On the DB25 connector, take a voltage reading between pin #2 and pin #7 (transmit pair) and between pin #3 and pin #7 (receive pair) - the Transmit pair will read approximately 12 volts DC, the Receive pair will read some odd voltage.

4. If there is more than one COM port on the computer, use FastCAM to send a file to the COM port specified as the Primary Serial Port (see below). The voltage on the Transmit pair of the Primary Serial Port will fluctuate while the file is being transmitted and will return to 12 volts DC when it is finished.

5. Check the DB25 connector on the milling machine in the same way.

6. Wire the cable such that the Transmit pin (pin #2 or pin #3) of the milling machine is connected to the Receive pin of the computer. The Receive pin of the milling machine should be connected to the Transmit pin on the computer. The common pins (pin #5 on the DB9 and pin #7 on the DB25) should connect to each other.

FastCAM Software
1. Set the parameters in the off-line software.
(similar to the machine control)

FastCAM I - from the MAIN MENU, press F10*UTIL, F10*PARAMS, F9*CTRL

FastCAM II - from the MAIN MENU, press F7*PARAMS, F9*CTRL

2. Use the arrow keys to get down the list to change/verify the parameters. (use the F3 key to toggle between the options.)

Primary Serial Port is ....................COM1
COM1 Baud Rate = .....................19200
COM1 Parity; Data and Stop Bits ...E/7/2
Secondary Serial Port is ................NONE

3. The Primary Serial Port selected in the software will have to be chosen to eliminate conflicts.

4. The Secondary Serial Port can be used to communicate with a second milling machine. Set the Secondary Serial Port to the one not used as Primary. When sending a file, choose the proper COM port (milling machine) by pressing the F1 or F2 key.


Check the spindle drive for an alarm code when the spindle stalls, you can download the M5 manual from the Yaskawa web site drives.com to look up the code and the possible reasons/solutions.

thanks for your reply,

ı understood that ı can send any program with fastcam after ı set fast cam software and machine side, then can ı send any program? if yes how is the procedure, if you have free time could you explain to me step by step,,??(for example on fanuc system,,
1-REMOTE MODE
2-GET A POST FROM DESKTOP IN NC LINK PROGAM
3-CLICK TO SEND
4-START TO CNC,, after this machine will begin to operation, what's type ı need to send with fast cam?


and spindle driver does not any alarm or error, just ı think the machine spindle is BT40 but it is working so weak, that's why do we need to change any parameter?

Thanks a lot again

Best Regards

In your first post, you described the correct technique to DNC from the RS232 connection.

I think your problem is with the RS232 connection itself. The control tells you that is is "WAITING FOR DNC LINK" so it doesn't see any data coming down the wire.

Go back to basics - check each end of the connection, then plug the cable into one end and check the other end of the cable. When you have everything right, it will work.

An alternative to the serial communication is to put the machine on a network. LOTS faster, more stable, fewer errors, etc. Do a search for DOS Network Client to learn how to do it.
