OMRON UEP12V SERVODRIVE AND LINUXCNC

HELLO ALTOGETHER

FIRST LET ME INTRODUCE TO YOU
I AM 47 JEARS OLD AND I AM LIVING IN GERMAY (BAVERIA)
I HOPE MY ENGLISH SKILLS ARE GOOD ENOUGH TO TALK WITH YOU ABOUT LINUXCNC.

I TAKE NOTICE OF LINUXCNC FOR ABOUT ONE JEAR AGO IN A GERMAN CNC-FORUM.
AFTER SOME READING IN THE LINUXCNCFORUM I HAD THE LUCK TO GET OMRON SERVODRIVES AND
MOTORS, AND THE BEST I GOT IT FOR FEE!

MY COMPANY WRECKED DOWN A SPECIAL-PURPOSE MACHINE.

SO I GET ONE SERVODRIVE **OMRON R88D-UEP12V**
AND THREE YASKAWA SERVOPACKS SGDE-04VP
AND FOUR AC-SERVOMOTORS OMRON UE40030V-S1 400WATT 1,27Nm

SO I NOW DECIDED TO LEARN MORE ABOUT LINUXCNC AND SERVOCONTROLLING.

I AM ONLY A HOBBIIEST AND AN ASOLUT NEWBIE.

IN MY FIRST PROJECT I WANT TO BUILD A SIMPLE PEN ON OPEN PLOTTER USING THE AC-SERVODRIVES AND MOTORS.
LATER I PLAN TO BUY A CHEAP SMALL LATHE AND RETROFIT IT TO CNC, ALSO USING THE DRIVES AND MOTORS.

I WANT USE MESA-CARDS FOR THIS PROJECTS

THE SERVODRIVE ARE ALL DIGITAL AND POSITIONCONTOLLED (STEP AND DIREKTION SIGNAL)
I SEARCHED ON MESAS WEBPAGE WHAT CARDS ARE AVAILABLE AND SUITS.
I THINK BUT IM NOT SURE THE 5I25 ANYTHING I/O CARD AND 7I76 DAUGHTERCARD PCI HOSTCONNECT ARE THE BEST.
THERE ARE ALSO PREPROGRAMMED KITS AVAILABLE I THINK.
ONE 7I76 HAS 5 STEP DIRECTION CHANNELS AN ENOCER INPUT AN ANALOG +-10V OUTPUT FOR A SPINDLDRIVE AND SOME IN AND OUTPUT PINS
AND IS EXPANDABLE.
BUT WHAT ABOUT AN MPG (ENCODERWHEEL).
I WANT TO USE AN MPG TO MOVE AXIS
OK WENN I AM BUILDING THE PEN ON OPEN PLOTTER I CAN USE THE ENCODER CHANNEL FOR THE MPG, BUT ON THE LATHE I NEED ANOTHER ONE ENCODERCHANNEL.
BUT THE 7I76 HAS ONLY ONE:

AND IS IT POSSIBLE TO RUN LINUXCNC IN OPENLOOP BECAUSE THE ENCODER OUTPUT OF THE MOTOR ONLY GOES IN THE SERVODRIVE ANS IS NOT
LOOP THROUGH TO LINUXCNC.
THE SERVODRIVE ONLY OUTPUTS THE Z-PHASE SIGNAL OF THE INCREMENTAL ENCODER WHICH I CAN USE FOR HOMEING, BUT NOT A-PHASE AND B-PHASE SIGNALS,
THE SERVODRIVE OUTPUTS ALSO AN INP (IN POSITIONING SIGNAL) WENN THE DEVIATION CONUTER IS LESS THAN AS ITS PARAMATER SETUP.

WHAT DO YOU THINK ABOUT THIS PROJECTS I HAVE PLANNED AND WHAT ARE THE BEST CARDS

HERE IS A LINK TO THE SERVODRIVE MANUAL

support-omron.fr/pdf/SigmaI%20R88D-UEP%20User%20Manual.pdf

IN CHAPTER 5 YOU CAN SEE THE SERVODRIVE AND SERVOMOTORSPECIFIKATIONS

WHAT DOES LINEDRIVER INPUT 6ma AT 3V AND OPEN COLLECTOR INPUT 15ma AT -5V MEAN
CAN I USE 7I76 DIRECTLY (WITHOUT A RESISTOR)
7I76 HAS A BUFFERED 5V STEP DIRECTION SIGNAL, BUT IS THAT THE RIGHT SIGNAL FOR OPEN COLLECTOR INPUT OF 15mA AT -5V

DOES ANYBODY KNOW WHERE I CAN BUY MESACARDS IN GERMANY OR EUROPE

FOR YOUR HELP
THANK YOU IN ADVANCE
AND GREATINGS FROM BAVARIA
