[Emc-users] MESA 7I43 and 7I33 OR 5I20 and 7I33 OR MOTENC-LITE(7544)

I need to retrofit an old CNC Lathe machine with SIEMENS Servo Motors. The servo drives accept +/- 10V as velocity command. My question is which of the following combination is suitable to be used for interfacing these servos and differential encoders. 1. MESA 7I43-P with 7I33 2. MESA 5I20

Peter, I would check the power supply wiring Note the 7I43 power connector is _not_ a floppy connector It is pinned out: 1 5V 2 GND 3 GND 4 5V Yea, I realized that right after posting the question. I just saw the connector and thought how convenient that was to use the same

[Emc-users] Mesa 7i43 and external power

Hi all, I am sure I just missed something simple here, but I am having the CPU board refusing to boot when I connect an external 5V supply. For purposes of testing I am simply getting the 5V from the PS for the motherboard. I have moved jumper W6 to the down position, W2 to the up position, and

[Emc-users] Mesa 7i43/7i33/5i20 questions

I'm thinking about buying a dead VMC and converting it to EMC using Mesa boards and existing analog AMP's and encoders and had some questions: 1. Is there any advantage or disadvantage to selecting either the 5i20 or 7i43 boards? The 5i20's PCI interface is probably more robust but people seem to
