AC Servo

Sorry for those few days of absence: /

This map (attached photo) has a 0-10v output. It should work.
I read that you had to connect a 12-24v power supply to pins 9 and 10.
I wonder how it works for reversing direction of rotation? -10v-0v and 0v + 10v?
How to do with a card that is only 0-10v?

Thank you

The 0 to 10V output on that card is intended for spindle VFD speed control
Its likely way too slow for servo use.

Some servo drives will accept a unipolar 0 to 10V signal plus a direction signal, but this is always problematic due to the lack of identical timing between the analog and direction signals.

If you wish to use a parallel port and this breakout board to interface to your drives, they will need to be run in step/direction mode

Edit:
If the servo is just for the spindle you could use either analog +dir or step/dir
(as long as you do not intend to use the drive as a real servo for spindle orient etc)
I suspect step/dir will be easier to setup

Ok thank you I start to see a little clearer.
Now it's how to connect everything and configure it.(link of manual www.machsupport.com/forum/index.php?acti...33543.0;attach=44811 )
Sorry if I ask stupid questions or already asked but I prefer to be sure
I enclose a screenshot of the manual on the login page in step / dir (I think)
I have to plug it in as a stepper motor?
PV? PP = Step? and PD = Dir?
I guess the 12-24v must also be connected to the servo driver?

Thank you for your precious help

Besides, it is possible to use step / dir in speed mode?

Yes, LinuxCNC supports velocity-mode step-geneation, ie the number passed is a step frequency not a position command.
