Sanitycheck my plan: ethercat + stepperonline A6

Category: EtherCAT

I didn't do anything too special compared with this guide  other than selecting "USB_CDC" for communication and then scanning on the available "Serial Port" options until the driver showed up. If yours doesn't, try a different cable.

Erste Schritte mit A6-EC Servo: 24 V für Bremse, Bremswiderstand und RJ45-Kabel?

Category: Deutsch

Hallo zusammen,um überhaupt erst einmal ein Gefühl für Servomotoren und die zugehörige Antriebstechnik zu bekommen, möchte ich mir testweise ein kleines Servo-Setup zulegen.Aktuell schaue ich mir dieses Set von Stepperonline an:A6 Serie, 750 W, 2,39 Nm, mit Bremse, 17-Bit-Absolutgeber, STO
www.omc-stepperonline.com/de/a6-serie-75...a6-ec750h2b1-m17-sto Dazu habe ich ein paar Verständnisfragen:
  1. Der Motor hat eine integrierte Haltebremse.
    Benötige ich dafür zusätzlich ein 24 V DC Netzteil, um die Bremse überhaupt ansteuern bzw. lösen zu können?
  2. Im Handbuch steht auf Seite 12, dass ein integrierter Bremswiderstand vorhanden ist.
    Heißt das, dass ich keinen externen Bremswiderstand brauche, oder ist je nach Anwendung trotzdem noch ein zusätzlicher erforderlich?
  3. Ich würde das Encoderkabel mit Batterie direkt mitbestellen.
  4. Beim RJ45-Anschluss / EtherCAT:
    Reicht dafür ein normales handelsübliches Netzwerkkabel, oder sollte man hier besser ein spezielles, industrietaugliches Kabel verwenden?
Hier noch das Handbuch:
www.omc-stepperonline.com/index.php?rout...rvo_drive_manual.pdf Mir geht es wirklich erst einmal darum, die Grundlagen praktisch zu verstehen, bevor ich später größere Achsen auslege.Vielen Dank schon einmal für Eure Einschätzungen.Gruß
Mücke

Sorry, I forgot that. Can you get a scope onto the spindle encoder index pulse?

Yes, I can jog the axis and tried simple MDI commands that work fine.

Looks good.

Can you move the axis while jogging?

When using the attached configurations from my previous post, the last current position is displayed.

What position is displayed when you turn the servo off and on again? 0 or the last current position?

I don’t think it can be the Z-axis clutch, as I have a glass scale on Z.
So a slipping clutch should either be corrected or, more likely, end in a stop due to following error.

Could the coupling between the Z axis motor and ball screw be slipping?

 This is one of the macros that isn't working for me. I've tried running them with Axis and it won't run either. They work with others, but I don't understand the exact reason.

Thank you. This brings up yet another issue, I have been trying to update but I don't believe I have a good repository. I keep getting an error saying the address doesn't have a release. I have attempted several different locations And I entered them into synapse. But I must be doing something wrong.

Firmware request : MESA 7I76EU + 7I85 + PWM & IOport

Category: Driver Boards

You can also just add ~220 ohm series resistors in the PWM lines

The main hazard is ground differences/HF noise causing negative
input voltages with unlimited current. a series resistor will protect against
this.

Yes I'll take care to put a BOB betwen P3 and the hardware until I grab a specific card from mesa store ;)

Thanks a lot, have a good day

Can't see an oword problem, but have added some oword path checks to help to see if it's just a path problem. qtdragon will complain if the oword path is not found.
