Need Help!- Fanuc 15M memory

[Rogz]

Happy new year to you all.

I have a Heian NC-432P with Fanuc 15M.

I have a job where the memory isnt enough for all the G-codes. I am currently doing like this that i am dividing up the program in different parts. But it takes a lot of time to erase and sending it to the CNC all the time.

So my Q is : How can i do so i am "feeding" the machine with data from my computer.
Or if i can upgrading the memory to bigger capacity?

Does the machine's control have a TAPE mode? If so, then it will be relatively easy. If it doesn't, that doesn't necessarily mean that it can't, but the majority of the Fanuc controls from that period used TAPE mode to DNC (drip feed). Post back with what modes are available and I'll send you the information you require.

Regards,

Bill

There is MDI , TAPE , MEMORY , and EDIT.

I never used the tape although...

Thanks for the reply.

Rogge,

If you already have communication between your machine's control and an external device, ie PC, then you should be right to go. DNC or drip feed as its often referred to as, is accomplished by using TAPE mode. You need to use Comms software on the PC that has a DNC mode. but it is very similar to just sending a program to the machine's memory from an external device. I prefer software that allows the PC end to be got ready first and waits for a handshake signal from the machine to initiate the DNC session.

The operation of the machine will be identical to if you were running the machine from a paper tape, but without the tape. When the PC is made ready and with the machine in TAPE mode, press cycle start to start the session. All functions of the machine, such as Single Block, Optional Stop, Feed Hold, Block Skip and all the override functions operate as per normal; the only limitation is that if Sub Programs are called from the main program, the Subs have to be loaded into the machine's memory.

If you don't have Communication between the machine and the control, then the following information will apply.

To establish comms via RS232, set the following parameters and either buy or make a cable configured as per the following instructions. If you make a cable use shielded cable with at least 3 wires and a bare wire trace. The trace wire will connect to pin 1 at the machine end. (see cable pin out below)

Post back if you have any problems.

Regards,

Bill

The above cable configuration is for software handshaking (Xon Xoff) and the PC communication software has to be set to match the settings of the machine's control. Accordingly, configure the comms settings of the PC software as follows:

Baud Rate 4800 (Suggested starting point)
Parity = Even
Data Bits = 7
Stop Bits = 2
Handshake = Software - XON - XOFF

Check with Memex or tulip for memory upgrades for a lot cheaper than fanuc.

I have done the upgrade from memex on a 15M and was very happy.
