Dear Experts
We have Okuma VMCs of Models MB56VBR;MA650-VBR;MILLAC 4VA
Request to share signal details or addresses to check issues related to Cycle Start, Feedhold etc
Additionally if other technical/maintenance details may also please be shared
Regards
hy, pls check attached osp300pdf's, about using "osp io monitor.exe" ( located on right toolbar ) :
... VIRD[1210]=1 means door is close
... VORD[16]=1 means that machine is in lock mode
* examples are for lathes, but mills share same osp, so there are similarities
different machines have different signal maps
you can check status for single block, block skip, override value ( for example you can check if override is between 80 and 120% ), monitoring, coolant, etc / kindly :)
ps : if you wish to see what others have done, then search for vird & vord on the forum; i believe that maybe also vdin & vdout can be used, but i don't have experience with those
Thank you so much, shall check in the machine once we resume
Thanks for sharing pdf
Today we could correlate few points out of the pdf
Request your suggestion for the following as we are just not familiar with OKUMA CNC and PLC :
1. Error 4717 alarm D Door condition unusual 1 in Okuma OSP P200MR with D300 win MA2 013A PLC
Help screen indicates
ATC = Magazine Door
ATC1 = 1st Magazine Door
ATC2 = 2nd Magazine Door
ATC3 = 3rd Magazine Door
ATC4 = 4th Magazine Door
APC = APC setup door
Door = Operation door
Pl revert if all 7 signals mentioned above are ANDed in PLC and error comes if any of the 7 signals go low - if yes, please let us know how to search these addresses related to Door under I/O monitor as Label to search is unclear
Output QX0534.1 under PLC monitor is off ie 0
Can u please tell on how to check condtionons to satisy this output QX0534.1 under PLC Monitor
We are finding Libraries, data type, logical POUsand physical hardware on left hand side
2. Also if u can please explain meaning and usage of Change mode PLC control mode, spec mode, PLC spec mode etc under Display change
Warm Regards
H Rishikesh
Please attach a photo of the screen with an error.
And I will try to explain to you
Thanks for your response
Two inputs viz Front door lock &operator door close were not coming together hence output for front door close was not getting ON, we could resolve the issue
If u can please respond to other queries mentioned above
Regards
I can assume that this is an operator door error
1. Error 4717 alarm D Door condition unusual 1
An electromagnet is installed in the lock and there is no confirmation of its unlocking
iFDCL-Door Close confirm
iDRRP-Door Lock Pin ON Confirm
You can watch them relays in the POS unit usually fail
Provided that you have checked and adjusted the operator door locks
hy rishikesh :)
try "IF [ VORD [ 0221 ] EQ 1 ] "Quote:
how to check condtionons to satisy this output QX0534.1
look not only at "label" but also at "comment"; you have to check each item, since is not possible to search in all fields at once ( at least i could not do it )Quote:
how to search these addresses related to Door under I/O monitor as Label to search is unclear
if you get tired of this method, then you may check all displayed items at once, by opening/closing the door from the panel, and looking at the screen, so to find which item is changing color : so you have to toogle the signal, and look at the item that is flasing on screen; this method allows to check 15-20 items at once
searching may take a while ... be patient, search only 5minutes each day, etc :) try asking your okuma dealer about those, maybe you are lucky :)
enabling/disabling acces to the possibility of forcing signals and/or using a maskQuote:
meaning and usage of Change mode PLC
... if it is disabled, then you can only check the values
... if it is enabled, then you can also change the values, and use a mask to force permanent signal states ( for example to have a faulty equipment to output an "ok" signal, so you could continue machining until service team will arrive )
in most cases, it is enabled when new hardware is installed, or when cnc is delivered, or during remote service sessions, etc
i have also seen those areas(like a highlighted matrix), but so far i have never needed to change something thereQuote:
spec mode, PLC spec mode
i guess that is like a map that shares same info like the management data card
please, if i may, how did you fixed it ?Quote:
Front door lock &operator door close were not coming together hence output for front door close was not getting ON, we could resolve the issue
i have seen big doors erroring out during machining ... too heavy for the small locks / kindly :)
Thanks you for your response
In another similar machine, we found inputs for Front door lock and operator door close were coming together but not in this one, hence adjusted switch a little then started getting both inputs hence with M32, output got on
We feel all 7 inputs of various doors are ANDed in logic then please let me know how u thought it to be only due to operator door?
We tried to reach out to local Okuma but to no avail, hence took about 4 hours to fix this issue
Thank you once again
Thanks you for your detailed response

We feel all 7 inputs of various doors are ANDed in logic - whether our understanding is right?

As informed u earlier, we dont have any prior knowledge on Okuma, although we have worked in Fanuc and Siemens hence sorry for asking u very basic things as below :
1. "IF [ VORD [ 0221 ] EQ 1 ] - where to type this IF statement and what is the meaning of this IF statement to understand correlation with output QX0534.1
hello, i suppose that the safeties has to be ANDed ... not my area :)
maybe you should look for a screen, that may show status for all required signals : for example, for a parts-cather ( on a lathe ), there is a screen that allows to manually advance/retract it, and also shows the signal state; like this, for example, if you advance it, then also the "advance" sign has to ligth up, otherwise something is not confirming ... because all required signals status is displayed, then should be easy to spot the problem
i can not share this screen, because i don't have acces to a vmc+auto-doors, but should look like attached 01
sergeyrussa shared those iFDCL and iDRRP; i really have no clue from where he has those, but i also searched them, and i found attached 02; pls find also attached pdf file, about automatic-doors
i guess you wish to hunt for all critical signals, and check them by using vird and vord : i shared, in image 2, the arguments for those functionsQuote:
"IF [ VORD [ 221 ] EQ 1 ] - where to type this IF statement and what is the meaning of this IF statement to understand correlation with output QX0534.1
for example, next code checks if operation door is open; you can put it at the begining of the program / kindly :)
Code:IF [ VORD [ 0221 ] EQ 1 ] NJUMP
M0 ( check the door )
