The drive manual shows that the alarm output is an optocoupler
This can connect directly to the 7I76UE field inputs


+24V --> ALM+
ALM- --> 7I76EU field input

 

Interesting concept, one driver supports 4 motors.

No problem with Canopen over ethercat. It is actually required for the device to use
Canopen over ethercat, CoE with linuxcnc. So all devices use it even the Beckhoffs.
No problem with coexistance.

There is no specific driver for the 57E but since it almost certainly is a cia402 drive there is a general driver to use.
The only a bit unique thing is to figure out the PDOs for motor 2, 3 and 4.
Can be done from the manual or from the drive itself.

Mesa 7i76 should have 4 analog inputs (do check if EU has) that you can use for amplifier fault at 5V, but it will require some HAL editing.
Should be field inputs 0-3

Hi,
i like to build a new control cabinett for my cnc machine. based on ethercat.
I am currently in the planing stage. I think the Lichuan CL57E are a great fit since from what I can read they can already do prettymuch everything I need. upto 4 closed loop stepper and tons of DIO.

My problem is that it says it is canopen over ethercat. Does that mean other ethercat devices also need to be canopen? Or can I just connect my Beckhoff EK1100 and my servodrive to the same ethercat line?
Are there already drivers for lichuan ethercat devices?
Thanks for your help

Meinst du ein mechanisches Relay?

I maintained series cabling, switch is just between rpi and first ECT60. Only purpose for switch was isolate Ethernet disconnect to side or other. After adding switch i cant see ethernet disconnect messages in rpi kernel logs any more. I am having RTT60V202 versions.

 

Review this working hal file against yours
github.com/rodw-au/showstopper/blob/master/my_Plasma.hal
nowhere is there a loadrt motion command

Hypersening allows you to probe surface so quick its scary, I use Hypersensing to set tool height offsets on my router had to modify the g38s with digita on offs to stop the probing erros i think theorically it is the most accurate method with known physics.

Interesting feedback but may not be relevant here. Any switch or relay introduces hysteresis. Switches have hysteresis from physical travel mechanical relays add delays from contact travel, even digital relays have hysteresis between their on and off voltages eg turn on at 15 volts and off at 5 volts. Hypersening on the other hand uses moving averages and eliminates hysteresis because it is triggered at a voltage threshold you set and turns off as soon as the voltage is trending downwards hence your scary probing times!

You need to add the vid and pid item in the <slave line.
You find the numbers with "ethercat slaves -v"

Thank you so much, now looks good.
Can someone help me with "setp cia402.X.pos-scale 3600" value?
I've this type of motor with the same encoder: EMMB-ST-87-M-SM (X), EMMB-ST-87-M-SMB (Z1,Z2,Y1,Y2).
Z1, Z2 5mm/rev; X, Y1, Y2 180mm/rev.

An open source programmer usually only sees the problems and errors that users have, but very rarely reports of success.

So I would be very happy if you could give me a little feedback.


OK so yeah I am guilty of exactly this, and most of my errors are my own doing! 

For me RIO has allowed me to update my two wood router style machines with closed loop to the controller, after my MESA cards died, not trash talking MESA in any way, where I live its hot and humid, VERY hot and VERY humid, for 75% of the year, electronic boards tend to not particularly like those conditions. 

Moving forward my next machine to retrofit is a 2.5 Ton milling machine, I have no real concerns with doing so, I can setup closed loop control (Brushed dc servo's) for all three axis, and even the spindle can be closed loop to linuxcnc as it is also brushed DC, around 200 Volts. All this just works in RIOCore, yes a 200 V 4KW Brushed DC motor is a little spicy but I only need to worry about the power stage, its still just a motor, and RIOCORE has it covered. 


Cheers.
Russell.



 

Hello everyone, I am relatively new user here. I was trying to test my is620n drives from inovance with linuxcnc ethercat and kept running into problems.
I am using the hal file and xml from another user here on the forum but slightly modified.
The problem I am facing is that the drive stays in PREOP and I am not able to get any motion out of it.

I am posting my files here, thank you!

 

Wenn das Alarmsignal des Steppmotors nur 5 V liefert dann schalte doch mit dieser ein Relais das die 12 V Ein und Ausschaltet
und lege die 12 V auf den PIN

Juergen

Start with controlword, statusword, opmode and opmode-display.
 

Ich habe das Support Manual.

"The 7I76EU field inputs have a nominal input resistance of 10K Ohms to field power ground. 7I76EU inputs sense positive input voltages above a preset threshold. For best general purpose use, default input threshold is 50% of the field power supply voltage with 10% hysteresis. That is with a 24V field voltage an input must be brought to 60% of 24V= 14.4V to be sensed as high and then brought to 40% of 24V = 9.6V to be sensed as low.These accurate thresholds and hysteresis allow high speed field signal detection whilemaintaining excellent noise immunity."

So wie ich das verstehe müssten bei 12V mindestens 7,2V anliegen um ein "High"-Signal zu erhalten.
Damit komme ich ohne eine kleine Verstärkerschaltung nicht weiter.
Richtig?

Als Schrittmotor möchte ich gerne diese verwenden...
