Hi All, During our bench testing we were running a test program, spindle was running in auto and servo motors are turning as per the program, all working as it should. Servo motors are not yet mechanically connected. We happened to push the spindle stop button, (not the E Stop) which stopped the spi...

Will this parameter file work for Oak too?

Seems like I missed the part in "Encoder Basics" where it is noted that TTL encoders are not suitable

Heidenhain ERN 1120 is TTL

Thanks CNCSNW. Pairs are black & white, red & pink, green & blue, yellow & orange. I have found a SUMTAK data sheet for the Heidenhain ERN, which is more accurate to my wire colours and seems to match pairs above, hopefully this works. https://lh3.googleusercontent.com/pw/AL9nZEUf2zf...

Hi All, I am using a Heidenhain ERN 1120 on my spindle motor, as that is what came with my CTEK VMC. According to the data sheet, that I found and as Marty has previously posted (below) the ERN series has grey wire for the B channel. https://centroidcncforum.com/download/file.php?id=15401&mode=v...

Hi All, I am using a Heidenhain ERN 1120 on my spindle motor, as that is what came with my CTEK VMC. According to the data sheet, that I found and already posted here, the ERN requires a grey wire for the B channel. Problem is I don't have a gray wire out of the encoder! I have Blue Yellow Brown Gre...

@cncsnw thanks for engaging, much appreciated!

We run 220V and 380V in South Africa, looks like 220V single phase for the servo drives is ample.

I have spare contactors so I will run one on the VFD, I assume I can wire the VFD contactor coil through one of the servo drive contactor NC contacts?

Hi All, Our project is a CTEK KM80D VMC, made in Taiwan, it has 5mm pitch ball screws directly driven by 1KW motors on the three axes. Z has a counter weight. Spindle is 7.5 HP 8000 rpm driven by RICH VFD. Machine came without servo drives and controller. See link in signature for images and build p...
