Chinese Servo Drive Calibration XP200

Category: Milling Machines

I just received a XP200-30pl servo drive and I am now looking for a manual in English. The documentation sent was a one page sheet all in Chinese I noticed in this thread that there is a I/O drawing in English. If someone has a English manual for the XP200 please send let me know.

Thanks

Fanuc Serial Pulse Coders - Red cap servos, mesa 7i76e, how to?

Category: Driver Boards

I have not found any formal documentation on the encoders or any note in the machine’s schematics, so I don’t know.

You did say in a previous response that you thought my encoders are 1M units per revolution, in response to a post where I provided the model number.

Tomorrow I will do more testing - I will try to verify one complete rotation and see how the counts check out.

The machine does not have internet access (I blacklisted e1000e on Debian).

Ubuntu (the PC is dual-boot Ubuntu 24.04 LTS (for everyday stuff) and Debian LinuxCNC) has internet access, but it is annoying to copy the file.

Fanuc Serial Pulse Coders - Red cap servos, mesa 7i76e, how to?

Category: Driver Boards

Back from holidays, finally got to dig a little deeper with the oscilloscope. I managed to figure out the polarity of the connections and alas, I am now receiving the response from the encoder!

Some values are showing up on my HAL Show and now I need to figure out if everything is working correctly and whether or not I need to create a custom setup string.

After a slight turn (a few degrees) of the motor shaft in the reverse direction my HAL show reads:

 

Suggestions for next steps are encouraged.

Lichuan Ethercat Nema23 closed loop stepper motor XML configuration

Category: EtherCAT

I have the same drive, did you solve this problem? I have an xml from lichuan that appears to be designed for use with Beckhoff software, I don't know if it will work for Linuxcnc

Rapid speeds

Category: Basic Configuration

In both cases, if the encoder is scaled correctly, the encoder velocity will read
machine units per second for linear axis and revolutions per second for spindles.
(there's also revolutions/distance per minute encoder velocity pin)

So if you can command a maximum speed (10V on an analog system)
you can measure the velocity/rpm with the encoder feedback.

For linear axis you will have disconnect the motor from the ballscrew to do this test
also the maximum actual speed will be 10-20% less than the speed at 10V
because the PID loop needs some overhead.

Servo Wiring and Tuning detailed How To example Mesa 7i77.

Category: Advanced Configuration

If the machine uses mm units, 200m = 0.2 mm/division
and a velocity of 1 means 1mm/s

In halscope what are the units ?
For example if set f-error to 200m/div what and i see 1 div how this translates to mm ?
Also in cmd-velocity if i set to 1/div how this translates to mm/sec ?

I have seen a post by @andypugh that showed an alternative method of pid tuning
know anyone the link of this post ?

How can i find rapid speeds of machine ?
Is there an automated script that measures displacement/time to calculate rapid speed ?
Also how can measure max rpm of spindle with encoder installed ?

Coordinate system in GUI does not match machine

Category: Basic Configuration

None of the above are OK, this is how it is usually done, almost always
forum.linuxcnc.org/38-general-linuxcnc-q...moving-axis-s#309571
You can have it as you want/like, but that will cause issues with every CAM you might use
Here is also the homing stuff
linuxcnc.org/docs/html/config/ini-homing.html
And to reverse motion to any axis, use the StepConf wizard to edit the existing config (or make a new one, you can have many configurations for a single machine), on the pinout page there is a check for reversing the signal to the right of every pin.

Maus funktioniert nicht bei Spindel Start

Category: Deutsch

If the mouse fails whenever the spindle is running, the problem is more
likely to be caused by EMI from the spindle drive rather than the relay.

I would try (as tommylight suggested) a ferrite bead = common mode
choke around the 3 (UVW) spindle motor wires and a line filter in the
VFD AC supply

So jetzt geht alles bis auf Spindel AUS bei mir auch. 
Hab mir bei ner Flasche Bier jeden einzelnen Fehler entweder in der Machine.hal oder Handrad.hal auskommentiert, so lange bis alle wichtigen Funktionen funktionieren. 
Für das Spindel AUS brauch ich wahrscheinlich nochmal Bier Nachschub.

Coordinate system in GUI does not match machine

Category: Basic Configuration

Hello everyone,
I probably have a very simple beginner's question that I just can't figure out how to solve.

I have a milling machine with x,y and Z travel and my home coordinate system is at the top right. I assume that you can do it this way or is this fundamentally wrong?

So that my coordinate system looks like this:
File Attachment:


But the coordinate system in the GUI shows the opposite.
File Attachment:

Video for better explanation: Link to video

I guess that my z-axis is the wrong way? Or the Y-Axis? And I also don't know which parameter I have to change in the ini-file (see attachment)?

Maybe someone can help me out with that.

Best regards
