I have a Takisawa TC-2 equipped with Fanuc 15TF and I am getting following alarms
OT007 X+ OT(Hard)
OT008 X- OT(Hard)
OT007 Z+ OT(Hard)
OT008 Z- OT (Hard)
I went thru Fanuc 15TF maintenance manual but did't find any help as G flag address are different. Also I checked the ot limit switches in machine but OT limit switches are wired in series.
Even parameter 5201 was not found in cnc system to disable OT limit switches. as after parameter # 5200 then #5210
Somebody help me & provide me the Connection manual Hardware suitable for Fanuc 15TF.

Usually all OT at once are due to fuse or DC power failure somewhere to the OT SW's.
These are active low, so without power they all show activated.
I should have the manual, if you PM me an email add.

Hi Al, I have the same problem as Rai, ot007 and ot008 overtravel alarms in my 15a. I know this post is from a while back but do you think you could also send me a connection diagram if these limit swith connections?
thanks,
Brandon

Brandon, interesting that your email address is plccenter.com. I had conversations with their management about setting up a cnc testing facility. Don't they have manuals?

Yeah we have a lot of good manuals on these machines. I just havent been able to find a connection diagram that shows where these physical overtravel switches connect to. Any Ideas?
