Hitachi Seiki TF20 Help ! ! Please
Hi , this is my first post on this site so i apologise if it is a bit long winded.
C.N.C machining is relatively new to me , i have only got 4 ish years or experience and only 3 on this machine. All three without problem . Until now...
Could any of you guys please help me with a hitachi seiki lathe type TF20 with Fanuc series 21-T controls ? The problem started when a part came free from the chuck whilst being machined. This has happened numerous times , all without serious consequence . This time however , after hitting the emergency stop button , i noticed a torque alarm , i didnt note the number as it cleared too quickly! I then moved the turret clear of the jaws and tried to zero return the machine as usual , but at the end of the Z return cycle , it stops and shows
506 over travel +X
It does the X axis first as normal without problem , but near the end of the Z cycle the alarm triggers , showing an overtravel on X. Strange?
506 is the hardware overtravel , but the limit switch is not hit by the dog.
Also there is an external alarm , 1005 , for which there is no reference in the alarm list in fanucs manual , and i do not have the maintenance volume of the seiki literature.
I have tried to remedy this by the P and cancel buttons on power up , but this does not work , nor does adjusting the x or z axis with the 1850 grid shift parameter , the machine just halts at the end of z zero.
Should i be able to set the reference point by software or is it necessary to adjust the ball screw ( a procedure i know next to nothing about!)
Thanks in advice people , any help would be , well , really helpfull !!
Great site by the way.
Cheers
HITACHI SEIKI TF20 FANUC 21T PARAMETERS
Here is the parameters for your Hitachi Seiki TF20 with FANUC 21T.
NOW, We have the same Hitachi Seiki TF20 with FANUC 21T control and WE NEED THE LADDER BACKUP FILE, because we have ROM Initialize troubles and we can not start the lathe.
I just attached the 4 files we have but we need the LADDER file.
It seems like must be 5 files for this backup, 21nc, 21off, 21pmc, 21pro but our technician says LADDER FILE IS MISSING. HEEEEELP US PLEASE...!!!
