drip feed and index at same time.

[bigtown]

(Daewoo DMV 4020D) and controller (Funuc 21I-mb) does not have enough memory to run from controller. I have to drip feed the program from the card.

My problem is to run from the card I have to change parameters. I also have to change parameters to run the index head. these run on the same parameter so I Have to choose which the index head or the card.

I have a program that requires both the index head and the memory card.

Is it possible to ues both at the same time on this machine???

the same parameters? which ones exactly?
do they work ok when run separately?
i.e.
can you run from the card with normal drip feed?
can you run the index head with normal drip feed?

Yes I can do both.

I need I/O channel 0 for 4th axis and I/O channel 4 for card.

Therefore, I can not run both at the same time.

Does this make sense???

I feel like it sould be possible to do both.

[fordav11]

ah I see. The I/O channel is conflicting.
There's not a lot you can do there.
It should be possible to set your 4th axis to I/O channel 1 but you will need help with it since there are probably a lot of parameters that need to be changed.

It seems like this would be a common set-up, running an index head with while feeding off the card.

What would be the most common fix for this issue? More memeory on the control?

The control needs to read off the card the program is too large for the memory. the control also needs to read info for the index head.

Assuming you don't need feedback from the Index head, change parameter 110 bit 0 to 1 and you can control the I/O devices separately. Parameter 20 controls the Input device, and Parameter 21 controls the Output Device. Thus, you can Output to the RS232 port and Input from the card.

This sounds very logical

I am going to attempt it and will return my results for future searches

Thank you,

As a caveat, if you have to change this setup very often, you can use "Programmable Parameter Entry" to change parameters from the program, rather than through MDI.

The following will set both parameters 20 and 21 to 0 for I/O through the RS232 port.

The following will set parameter 20 to 4 and parameter 21 to 0 for input via the card, and output through the RS232 port.
