hurco hawk 30 retrofit

hi
I need some guidance on identifying the motor in this machine.

manual gives below information

it doesn't cover serial number of this motor , esp encoder . anybody has similar motor or relevant information?
thanks

Pin 13 to En0+

But do please wait for PCW's confirmation.

No, I think the drawing is correct because the chart says the enable is active low
So
EN0+ to pin 14
EN0- to 24V ground

So drive enable grounds PIN 14 when enabled

I need bigger glasses !
Thank you Peter.
Deleting the post with wrong info.

Well assuming the chart is right...

Note that in most cases you can easily check if an input
needs a NPN (sinking) or PNP (sourcing) signal by measuring
the input voltage when unconnected. If the pin reads a large positive
voltage when unconnected, it needs a sinking driver (pulls to ground)
If the pin reads close to 0V when unconnected, it needs a sourcing
driver. (pull up to 5V,12V or 24V usually)

So far from experience, if a drive has a 24V pin ( or 5V or 12V ) it will require all input pins to be brought to that potential to activate, while if they a have a GND pin they would require bringing inputs to ground level to activate. And from that chart i saw a 24V pin, so ......

HI All,
I was able to run the machine finally . All axis and spindle are working . But I have an observation on Y and X axis . During Jogging I am finding that axis is jerking . I have taken the Halscope plot . See attached pics for reference

enlarged View

Logs are also attached .

To verify hardware and connections I scoped using oscilloscope . encoder pulsed looks clean . (no gaps or missing pulses .)

Z axis is working OK . Anybody faced this issue before ?. Please guide.
Thanks
Riaz

Do the jerks happen at the same locations?

It's repeating in regular intervals throughout travel. I checked ball screw it's free .No catching any where.

Linear or rotary encoders?

All of the Yaskawa drives I worked on need a gnd to activate.
