Apologies if this is getting tedious... Have removed PC front panels (with stuffed ribbons behind) and comms timeout error disappears. Run FANUCMS.exe successfully. HOMEing axes (no faults) produces: X = 000.038 Y = 169.995 and Z = 299.038. I am informed these are normal values. When HOMEing axes (w...

And another. . . . It would appear that each remedially intended action can elicit some new reaction from this Triac 200. Without disturbing rack PC or wiring (to the best of my knowledge) and following the same bootup sequence, Fanucms.exe now reliably hangs as follows: MSDOS (6.2) and Fanucms.exe ...

To Denford admin Thank you for these. Among some of the sheets I can recognise definite correspondency to our installation here. Will keep these on file. Since last post the have shortened some overly long ribbon cables stuffed inside rack PC and Triac 200 is now running reliably. No following error...

UPDATE: Further to the above and with the aim to fix the above on limited budget: The Triac 200 installation has its original PC (in rack form) and the original PSU (60Watts). It has a 3.5" floppy drive. During its life an internal hard drive was added but without uprating the PSU. This week I have ...

Hi Thank you for that prompt reply! Our Z axis has the counterbalance and all three motors are the same. Photo. Z of course is new. Accessible controls as follows: re pdf file on this post Balance, Tach gain, Time Constant and Damping Drive and board are currently back in and the workshop engineer i...

Thank you for your post. Our machine uses ML 2340 A-10 motors. (2 phase servo with shaft encoder feedback) Photo. Since my last post I have done the following: I have been running the Y axis motor (out of its axis) using a function generator input to the user I/O with scope attached to link1 (veloci...

Further:
Obtained a BL Brushless Servo Drives User Guide from web.
Next will follow "Tuning the Drive without a positioner" as per page 29 with an external signal source and motor out of machine.

We have an early Triac 200 CNC centre. Inboard rack PC has dongle on parallel port and 3 x BL30 drives. Running Fanucms software. Recently the Z axis stopped working altogether and the Z axis motor (ML2340 A-10) has been replaced satisfactorily and we are now working again. (Our longterm solution wi...
