Fanuc 16MA pmc parameter transfer

[davehall]

Hi All,
Working on a Mori Seiki MV40 which has lost the pmc parameters. Have tried to reload the parameter backup file according to the Fanuc manual - just sits there flashing EXECUTING. Am able to dump the ladder file OK. Tried power up & O+X to clear RAM. The pmc parameters start at 60000 and I'm able to enter values by hand. Does anyone know the connection between the 60000 parameter numbers and the T C K D locations thanks?
regards...

It's been a while since I tried doing this, but see if removing some of the header information will do the trick.

Example:

&FWPMC              :%
N60000 P10000
N60002 P12500
N60004 P31250
N60006 P12500

To this:

N60000 P10000
N60002 P12500
N60004 P31250
N60006 P12500

If I remember right, when successful you'll see the parameter number counting through the list near where the flashing EXECUTING will be.

Thanks very much for the reply. Yes, someone had removed the header in the pmc parameter file, I set bit K17.1 to 1. Reloading is not ticking through the lines on the screen as you mentioned although the comms program is counting them on the laptop. The only other thing I can think is if the file no requested in the Fanuc I/O page should be something other than 2.

On the PMC I/O page make sure the Channel is set to 1 if you are connected to the 1st RS232 port on the CNC. This usally get set to 0 whe all memory has been cleared. The Ladder is saved on EPROM so you really didn't load it. It won't load into ram till you set the 9900 option parameters. You mentioned that the header was removed, make sure the % sign is still there. The Fanuc control looks at the % to open the port. You need a % at the start and a % at the end. The first % opens the port and the second % closes the port so if you have 2 % signs next to each other at the top it won't load either. Hope this helps. Make sure PWE is on and you are in Edit mode. You can also try it in ESTOP

Hello drdos, that certainly helped thanks! PMC parameters now loaded. Will fix a couple of Z servo alarms & see how the Fanuc behaves.
