Check Parameter 37 bits 0-3 0=1st axis, etc. This tells the machine if there is a separate pulse coder that detects movement. WARNING: Disconnecting this may cause the axis to not move as expected....

If this happens at power on, it could be the unit with the "5" on the LED.(That unit is a servo amplifier.) Could be an issue with the servo amplifier of the power supply module next to it.

F148.6 "SA" is the servo ready bit from the control to the PMC. Your servo's are not ready. The machine could be in Emergency Stop, or an axis could be on a hard limit switch, or there could be a...

Have you recently had service on the machine? or did it lose memory? If the machine is older (90's) it might not have batteries. Compare parameter 1815. If bit 5 is OFF on the good machine, then you...

the software operators panel is under the OFFSET/SETTING screen. Hit right arrow, should be labeled OPR.

FANUC LH1 is not a valid control type. what year what the machine/control made?

it is an option parameter. if you have the original data sheets or parameter list, it can be reinstalled by FANUC. you can most likely find the option bit by searching online. No one will post it on...

Check your servos. Your 3rd axis servo has multiple alarms. Overload(overheat), Low Voltage, High Current. Most likely the servo PCB on that drive is damaged.

A bits are alarm bits on PMC side. If any are on, then trace in ladder to find why it is on. Or consult MTB. I believe alarms in the 1000 range are MTB alarms, not FANUC alarms.

stupid question: are all doors closed properly?
How about G8.0=1? This is interlock signal. Trace in ladder and find cause if it's a 0.

Check A bits in status in PMC. Trace in ladder.

Check FEEDHOLD.G8.5. It should be a 1. IF G8.5=0, check ladder to find out why

Flashing 9 on spindle? What kind of spindle amplifier is it? (Alpha, Analog, Digital) Which FANUC control is on the machine?

That normally indicates a bad servo module on the main PCB.

Parameter 1815 bit 1 tells the control your axes have scales. That needs to be on for the axes with scales, or the control will not move properly.

That's not a configuration issue. That's a corrupt memory issue. While swapping, your good control's memory has been corrupted. Most likely by being disconnected from the battery for extended period....

either display hardware issue.. or corrupt memory. If you have parameters backed up, you can try to clear memory to see if the screen fixes itself.

The encoders are the APC... 6Vdc? Unless each drive had a battery, these are most likely on the door.

C31= X axis (X)
C34 = Y axis (Y/Z)
C37= T axis (Z/P

The 4 cable wires are the motor power. Should connect to 5,6,7,8 on the drives there. I imagine X to X, Y to Y, the other to T. 5=Red,...

There is a switch, and if it comes off, it will lose that LED.

Change parameter 85 for 4th axis home position.

post a picture of your screen. The NMIC information points you towards the problem.

When does the alarm happen?

ladders vary upon machine, not upon FANUC model.

If they same issue is happening with the new drive... Then it's not the drive. Measure the resistance of the motor power U/V/W to GND with an insulation tester. It should measure above 200Megaohms....

A0? Are you sure this is on the Power Supply? Or is it on the Spindle Amplifier?

If this is on the Spindle Amplifier, the software has gotten corrupt and needs reprogrammed.

Are you looking at parameters?... or Diagnostics?

Same control as a FANUC 21. The MSC521 is just a FANUC control, with a Mori custom side that they install.

What kind of control is on the machine? Although the drive may be there, an option may need to be added in order for it to work properly. PLUS, the servo parameters will need to be set up.

Most likely one of the MMC boards next to the CRT inside the cabinet.

E44 HDLC RESPONSE TIME-OUT ERROR
COMMUNICATION TO CNC WAS INTERRUPTED DURING COMMUNICATION INITIALIZATION
CHECK CNC POWER...

That is a machine side alarm. Check for an A address on in the ladder, then trace it back to the cause. If you have a manual for this machine, it should tell you what 1002 means.

Unless you have a hard copy, or a special device that only the MTB has. You won't be able to read the ladder. The ladder is either on the ROM board or PC board.
