Yes, you should.

First, you should always turn main power to machine OFF before removing/replacing EPROMs. Use a EPROM puller, don't try to remove with anything else as you may easily break a connector. In my time...

FIRST CHECK OUTPUT FOR TOOL CLAMP, IF IT IS ON, THEN CHECK THE TOOL CLAMP SOLENOID FOR PROPER OPERATION, COULD BE BREAKER OR FUSE IF IT HAS ONE OR HYDRAULIC PROBLEM. TRY TO MANUALLY ACTIVATE THE...

I'm wondering if the machine may be in hard overtravel. If so, you must keep the OT bypass and start button pressed while you manually input the 900's. The screen that doesn't have the bottom line is...

Yes, manual reference of X, Y, Z axes should clear alarms.

As I previously wrote, you do not need a value other than 0 in parameter 1850 (grid shift for each axis) unless you want to change your positioning off of the grid on that axis only. You said you...

1850 is grid shift on each axis drive, but you don't necessarily need a value other than "0". 1815 is home setting, a "1", means that drive is already homed.
Which drive is displaying "8" on it...

Look at the setting of parameters 6751 to 6758 on the 2 machines, and compare to the machine not displaying cycle time.

Al and Tim are correct. 4 milliseconds is .004 second. .4 milliseconds is .0004 second. Your calculation is off by one decimal place.

HERE ARE NOTES I HAD FOR A HARDINGE WITH A 16-18 CONTROL:

K-BITS TO SET TO ENABLE TURRET SET UP:
K0.5, K2.2, K3.7 TO "1"

NOW BLOCKSKIP BUTTON WILL CLAMP/UNCLAMP THE TURRET
WITH REPEAT...

Try a setting of "1" for CMR, para. 1820.

Go to the diagnostics page and search for A1005, find the bit that is high A1005.1, a1005.2, etc. Then go to the ladder and search for the COIL with that address, it will lead you to the cause of...

No, not a specialist. I worked in the auto industry as an Electrician and also did some engineering work in that capacity, so I worked on many different type of machines starting out in a 5 million...

Yes, if it identifies whether it's motor, encoder, or amplifier, then it would be nice to have if it is affordable. I've never used one so I can't say. Fanuc parts used to be expensive, don't know...

I just noticed your comment about replacing batteries, I don't recommend it for this, BUT - if you do it make sure not to pull the main disconnect while doing it or you will lose all memory for the...

PS: The 751 is position detect error, which is the pulsecoder (motor), however the scenario with the brake could also cause it too.

The CNC alarms in the picture are consistent with high current alarm 8 on servo, so it's all pointing to that. Another thing you can check is coolant getting in the motor connector, but I doubt it...

I should mention it could also be a sticking brake, or not releasing as the control initiates. If you are drifted slightly below home position the control may try to move it while the brake is still...

Here are a few questions: 1) What is the error you are getting? 2) What page are you reloading parameters on (are they CNC or PMC parameters), and are you doing it manually? 3) What make & model is...

I'm still not understanding what you mean by "lost parameters". If you lose parameters the cnc will display faults. If you check the parameters and there is data there (not all zeros), then you have...

Check the inputs for tool holder returned on that arm. If you don't have documentation, look to see if there are proximity switches with LED's on them and compare #20 with the others. Also the input...

When you get a "memory card not exist" message it is referring to the PCMCIA card, not the memory cards on the control. If you have one (it is an option) then you will get that fault every time you...

Good! That's what the OT button does, except it jumps all the axes switches. If you were doing a home move when it OTed, then you need to check the home switch & dog on that axis, should never...

P-Cancel on start-up is only to cancel soft limits, for a hard limit there should be an OT Bypass button, if not try holding down the start button while you simultaneously jog. If no success, you may...

You can jump 24vdc (or whatever your control voltage is) to that particular input and it should take care of it, however somewhere there is a parameter or M-code that is causing your problem.

Go into ladder and search for the bit F62.7, it should eventually show you the line of logic for part count display and run time.

The parameter for ladder display is 60.2

TO DISPLAY NC DIAGNOSTICS, PMC DIAGNOSTICS, OR PMC DATA:
NC DIAG ARE DISPLAYED WHEN A @ IS SHOWN ON THE LEFT SIDE.
TO SEARCH A SPECIFIC NO., PRESS NO. KEY AND TYPE NUMBER,

I don't think the scale uses those batteries, just the APC. It is possible that there is a short somewhere in the APC battery circuit too. Scales can be problematic, especially in a wet environment...

Since the home reference was successful, I'd say replace the APC batteries, you never mentioned if that had been done. If you do this with power on you shouldn't have to re-home. Then cycle power and...
