We had an issue where by our monitor stopped working
Once fixed we now have an issue where when turning the spindle speed pot down it gets to a point where the spindle stops and runs in opposite direction
We also cannot perform a tool change as the spindle will not stop to allow locking
We have had the machine since 2011 and other than a few valves and belts we have had a great run
Any help would be greatly appreciated
Kind regards
Here are some issues that can happen Fadal machines and some tips to solve your issues. Typically this happens on early Fadal machines that the control cards were updated, but did not receive all the wiring upgrades found on newer Fadal cabinets.
Issue:
is running in Auto, and the machine will randomly go into SLIDE HOLD
A keypress will be missed. When typing X10.222 but the zero is skipped
Jog wheel loses pulses when turning the MPG
With the Calmotion LCD monitor replacement for the Fadal, ELE-0189, there are multiple background and foreground color settings. With the standard coax video cable to BNC connector there are only 2 colors, a foreground and a background color. The Calmotion LCD provides a jumper to choose what those 2 colors will be.
On the back of the LCD unit there is are button controls. The SW1 button (furthest from LED power light) will open the menu, and is also the select button. SW2 is moves highlight left, and reduces a settings value. SW3 moves the highlight right, and increases setting value. (SW4 not used) .
Open the menu on the LCD and select this icon to set the color levels:
Add the jumper that is next to the BNC connector:
Blue background and White foreground: Set red to 50%, green to 50% and blue to 100%
The Fadal 1090 keyboard controller uses an unkeyed and under sized header. So connecting the ribbon cable from the keyboard to this header allows several incorrect connections.
If after installing the keyboard replacement ELE-1784 the keyboard appears to not work. Most likely this is due to the connector not matching correctly to the 1090 controller. Most of the keys won't work, but there will be a few keys that do work but give the wrong output...
Here is a table of key press and the wrong displayed character on the screen. Press the key show and if it displays the wrong character on the screen then the reason for that is shown in the third column below. Correct the ribbons connection between the 1090 and the keyboard to fix the problem:

It would depend on your spindle drive. When a spindle drive goes in wrong direction after parts changes, it might need to be "Auto Tuned" The Fadal Maintenance manual will guide you through the autotuning procedure. This will calibrate the Spindle card's signal offset.... I would do this first. Then once that is resolved. you might need to then adjust the SPINDLE ORIENTATION FACTOR, in SETP. That changes the orientation speed. But first do the auto tuning to correct that issue first.
