its not at zero but we do have it turned down
We recently acquired a Toyoda FA450 III. Fanuc 16i control. We powered it up and cant get it to jog. Z axis needs to zero return, wont do that either. Are not getting any alarms. We can turn the...
I have recently acquired a torq cut TC4 with a similar but different issue:) I don't think the knock out is adjusted properly. I can not feel any force whatsoever when I hit the tool release...
Hi everyone. I have an 80's Ikegai Lathe with a Mitsubishi spindle drive and motor -DC. The spindle has no torque - and I mean NO torque. You can stop it with your hand. I have had a couple guys...
Hi, I just acquired a BP TC4 and I think there is a problem with the knockout system. A tool stuck in the spindle during a tool change and borke one of the plastic segments. I physically held a...
Thank you so much for the help. Thermostat was good. Circuit breakers were not tripped. There is a contactor to the right of the breakers however that the overload had tripped. Fixed it.
Some new...
Hello,
I have an old Ikegai lathe with a Fanuc 6T-B control. I was doing a parting operation when the tool grenaded and proceeded to mash the remainder of the parting tool into the material. It...
I will swap the drives and see what happens. what would the new "hiss" sound from the motor be if it was mechanical??
Al,
I thought about doing that. Since it has scales, if I remove the motor and jog it, what will happen? Will it just error out due to a following error?
For example - if I'm using the mpg and have it set on .01. If I move 4 or 5 clicks at anything but a snails pace it will begin to oscillate "jump back and forth". I can jog it back the other...
Mike,
I will call Monday.
I powered it up again to check a few of the things you listed and with the way cover back there is a noticable "hiss" coming from the motor. Almost sounds like an air...
Mike, you mentioned to call. Can you PM me your phone #
Thanks for the info. I dove under the way covers. Is the scale difficult to remove? Any tips?
Yes, It has scale feedback. Also, I didn't mention the fact that it was running fine until this occurence. It was mid cycle and all of a sudden started jerking and errored out. I will definetely...
I have a Sabre 1500 with an A2100 control. BDS4 Servo Drives. I can move the Y and Z axes just fine. The X axis however jerks, I'm guessing a servo oscillation. The control then errors out with a...
I don't have a feedback loss light on these drives. I powered it up again and the overspeed led on the x drive came on when it errored out.
thanks
So I took the power wires off the drive, still errors out. So we assume its the feedback cable. I pulled the way covers back and it has heidenhain scales on the x and y axes. Could this be the...
Thanks for the info!! The machine does fault out if I have NOT Aligned it and move the Y axis past the "point" . The cables are indeed gray. The power cable comes in to screw terminals on the...
I have a Sabre 1500 with an A2100 control. BDS4 Servo Drives. The machine powers up just fine and I am able to align the machine just fine. I can move the X and Z axes fine. The Y axis will move...
Here's the latest. We swapped motors between x and z and got the same error. X motor worked just fine on the other drive so motor and encoder seem to be fine. The drive is outputting voltage on...
Yes sir!

We did the motor disconnect routine and it worked fine. We used the HW to jog in small increments and turned the BS by hand. We were able to "move" the axis that way without errors.
Well, we got it cleaned up. Back together and still got the same alarms. I put 12V (battery) to the motor and it runs.
Does this typically damage the motor or is it a situation that it needs to be taken apart - cleaned - reassembled? Thanks Al
I played around with the handwheel this morning and just as you described I was able to jog a certain distance until it errored out. So if I turn the BS by hand and it sees the encoder you think the...
I pulled the brushes. They are about 3/4" long. There was some carbon build up, I cleaned it up - still got the same alarms
Help! I have a Hitachi 3NE-300 with a Fanuc 6T control. It stopped mid cycle with an x axis 410 servo alarm. I powered the machine off/on and if I try to jog the x axis via handwheel I get a 411...
