4.8.2.13
Code 337: Spindle calibration
This service code is used to calibrate the programmable spindle. You will need a tachometer to
complete the calibration.
4.8.3 Diagnostic Codes
The following codes are used primarily when diagnosing a problem with the machine. To get to any
of these codes go to Service Codes, press “C” and press the code you wish to view.
4.8.3.1
Code 54: Program Continuous Run
This Code runs a programme continuously without stopping for SET Z or CHECK Z commands. It is
helpful in running a programme for a long period to identify an intermittent problem.
1. Prepare a programme as you normally would.
2. Press MODE, SET UP, “C”, Code 54, INC SET. The program run will start automatically.
3. Press STOP to pause, and GO to continue.
4.8.3.2
Code 81: Keyboard Test
This code is used to check if the keyboard is functioning correctly. It allows you to test each key on
the pendant individually. When you press the keys, the corresponding box for that key will highlight
on the screen. The pendant will also beep, indicating that the key is working correctly. If one or
more of the keys do not work, the pendant assembly will have to be replaced.
4.8.3.3
Code 131: Manual DRO
This code is used to check the motor encoder and table encoders. Turn the X hand wheel or, if EHW
are fitted, turn the motor or ballscrew directly to display the encoder readings. E-stop the mill
before touching the motors/ballscrews. This code will display the actual DRO counts and the
raw encoder counts before the calibration and backlash factors have been applied.
4.8.3.4
Code 132: Electronic Handwheel Test
This service code tests the accuracy of the handwheel in fine and course modes.
Turn the X, Y, or Z-axis electronic hand wheel. The display should show movement as the hand
wheel is being turned. There should be no skipping and it should count smoothly while the hand
wheel is being turned. One revolution of the hand wheel should read 5mm (0.2”) in fine mode and
20mm (0.8“) in course mode.
4.8.3.5
Code 314: Toggle Test Lights ‘On’ in Status Line
This code toggles on and off 2 test lights that appear in status line on the pendant display. The top
light signifies if the master software is working. If functioning it should flash a green light. The
bottom light signifies if the slave firmware is functioning. It will appear orange in run mode when it is
processing information. Pressing the mode key will change this orange box to black. The orange box
will also change to black when the program you are running reaches the 3rd event from the end of
the program. If the firmware is locked up no keys will work. This code is useful for diagnosing
intermittent problems with the control locking up.
4.8.3.6
Code 319: Error Log
This code when turned on captures the commands that were sent to the servo system. It includes
items such as positioning commands, errors, stop and go commands, etc. It may be helpful for
identifying problems between programmed commands and executed commands. To turn on the error
log press the F6 softkey. The page forward and backward keys allow you to scroll through the file
one page at a time. The data forward and data backward keys allow you to scroll through the file one
line at a time. The data bottom key takes you to the bottom of the file and then changes to data top
which will take you back to the top. The file will capture data until the file reaches a size of
approximately 600 Kb. At this time the file is saved to a backup file and the original file is cleared and
data is once again captured. Once again as the file reaches a size of 600 Kb it copies over the
previous backup file.
The user can save the file to the floppy drive by pressing the F8 softkey. Once this is done, it
prompts you for which file you want to save to disk. The F1 key saves the current file and the F2 key
saves the backup file. To clear the files press the F7 softkey.
