Thanks John-100

Surge suppressor circuit board 1170-2 contains three varistors.
Which of them is correct for 240-250 volts power supply line:
NTE524V15 or NTE524V25 ?
Can anyone answer?

You right. My spindle would work without any air.

Hi there,

The machine is:

Fadal VMC-15
Model #: 914-15
Year of mfg: 1997

Spindle motor: Baldor 10HP, 3ph
Spec.: 37F71800073 X073 X173

The things sometime are not as they appear.
When I said that I can jog the X, Y and Z axis it is not quite correct.
Jogging the Y and Z axis makes those axis move.
However, jogging the X axis...

I removed the servo for X axis from the machine and performed some tests just to make sure that the servo is not the culprit.
I span the servo motor by hand – no resistance and no detectable noise...

Hi Tedger and thanks for your reply.
Did you read a second part of my post?
The ceramic fuse on amplifier board gets blown even after disconnecting entire X axis from the card.
Is it not the...

Thinks that happened from my last post.

Today I removed the board that the LED was dark, disconnected the wires from the bottom terminal

Thanks adaprecision,

It works.
In addition I have to use M45 after all next pecks.
So my program looks like this:

Thanks Sdfoiler.
I think I have to sleep over it and start tomorrow fresh.
The settings seem to be the same.
I am not sure about XOn and Xoff.
I also tried higher transfers (CD,9 and CD,10) for...

Hi Sdfoiler,

Thanks for response.
The answer is that it send the whole file without ever stopping.
No matter how big the file is.
I took YOUR file and attempted to run it using DNC command and...

Hi,

My laptop computer does not have a serial port so I use USB to Serial cable.
Linux recognizes it as /dev/ttyUSB0.
This works fine with CUTECOM program.
It is equivalent of Windows...

I fixed the memory problem.
This is what I did:
1- I removed an expanded memory board 1460-2A from 1400-5A and reinserted it into the slat.
This stopped scrolling.
2 – I...

It is some more info on the problem.


When first start the machine it shows :

Hi there,

Did not use the machine for about a month.
When attempted to power it I got the following on the moitor:

======================SPACE BAR FOR NEXT MENU

Thanks scadvice and denmar.
I zeroed the memory using:
DI <ENTER>
G 0 3000 <ENTER>
Chose function 5 = ZERO MEMORY.
Pressed MENU for 5 min. to exit DI mode but nothing happened.
So, I shut down...

I lost all parameters.
I re-entered them and every think is OK with one exception.
While working in MD mode the screen shows "TOOL 1.024 is in the spindle" (instead of...

I would like to thank every one who tried to help me to solve the problem and pinpoint to the specific device.
I think I definitely narrowed it down to the Baldor's vector drive.
In my attempt to...

Although the problem is still there I think finally I am getting some more meaningful data.
I removed the belt and it turns out when I use the keypad in the LOCAL mode the vector drive does not see...

Well, I still have a a problem and it is getting worse.
Now it is almost impossible to shut down the machine in a normal fashion without terrible noise.
It sounds like a rock crasher and I am...

In this configuration all three are 0.3 Ohm.
The results of readings for other configurations are in my previous post.
Some of them are also with wires from Wye/Delta relays disconnected in the...

My apologies. I made a mistake in taking the measurements of the resistance between the motor leads.
I just edited my last post to give corrected readings.
Sorry I guess I am just getting old.

I checked the voltage between pin 6 and 4 on molex connector.( See: molex.jpg)
The voltage is steady on each speed regardless if the motor rumbles or not.

Maintenance manual (page 271) says :

I verified that the ORIENTSP goes from 0 to 1 while magnet passes under the sensor.

I think that because the motor refuses to start rotating the spindle on time,
the sensor properly reports it...
