ER2 on Fanuc 10t?

[pld0vr]

I have a Mori Seiki AL2, which I have just connected. I'm not at all familiar with this control and I do not have the manual for the machine.

I don't appear to have any alarms, but I get the ER2 light, and I can not move/jog the machine. Any suggestions on this?

Also, how do I home the machine? Most of the symbols I can make out, but where is the all home function?

Here are some pictures. The text highlighted in white says "EMG".





Running the machine off of a digital rotary phase converter if that makes any difference.

Thanks for your help in advance.

After some looking I noticed that on the board in the cabinet I am getting AL-01. The best that I have been able to find online is motor overheat... that can't be right?

Alarm 01 (AL-01) Motor Overheat
Causes
Damaged motor fan, overload, motor cooler is dirty, loose connection.
Remedy
Replace parts, clean cooler, check connections, review cutting conditions



Any advice more specific than this?

The Estop condition is preventing any motion. The reason for the Estop is likely the AL-01 (Spindle Motor Overheat) that you found displayed on the spindle amplifier. The overheat contact of the spindle motor enters through connector CN2 on the lower RH corner of the spindle board that has the alarm LED display. If you remove the CN2 connector, you should see a normally closed (short) condition between pins 2 and 3 (reading into the cable). If it is open, follow the cable out to the motor terminal box. The overheat contact signals are on pins 7 and 9 if you have the 9 pin connector.

The "home" is marked on the rotary switch ZRN BTW. And agree with the Estop, nothing will move. Check to make sure the spindle motor fan is on and running, and you should have hydraulic pressure, even in this state. Make sure you do, otherwise your phase may be backwards.

Oh, and BTW, someone repainted that machine, should have been green and yellow

By "motor fan" do you mean the fan on the side of the machine closest to the spindle motor? If yes, then that fan is spinning in the correct direction (exhaust).

I have not checked anything else yet.

Fan should be on the spindle motor itself. It is quite common for the fans to fail from old coolant/dirt/grease/cat hair/ whatever floating around the shop. The stuff dries up and the fan can no longer turn. Then it blows some small 5-10 amp fuses in the spindle amp, causing the alarm you are getting. A simple cleaning will usually fix the fan, then replace the fuses.

Depending on what model SP drive you have but most have a thermal detection in the motor that goes back to the drive, if this is open it will give you the fault, also the contactor O/L went back to the drive input, may need resetting.

hmm... I don't see any fans at all on the spindle motor its self (mori seiki al-2)... just a huge motor connected to the transmission.

Where can I find these fuses? I have video of the machine running just fine right before shipment, so if there is anything that could have come loose in transit, that would probably be likely.

Thanks for the info Al, but could you please give me some more details on what you mean by this? Is there a relay or something to reset?

Ended up being loose pins in that connector inside the elctrical cover plate ontop of the motor.

Also, I was advised by the technician that I had come over that the reason my id plate on the motor is blank with just a few numbers on it, is because the paint has come off... due to heat/coolant or what have you. Seems to make sense.

Anyways, works great now.
