The idea is correct however, set the servo up in velocity mode and the velocity of the servo will be determined by the analogue inputs at 26,10,11.
The conventional idea is that 0 to10V will cause rotation in one direction, say CCW and 0 to -10V will cause rotation in the opposite direction. Referring to my own Allen Bradley and Delta servos
the primary direction (CCW OR CW with positive input) is programmable via parameters.. I imagine your servo is the same...good luck trying to find and program the parameters however.
Do you need counter-rotation?. In the early days I had Mach programmed to run in either direction, but then hardly, if ever, used it.
Start by doing some simple experiments with a simple 9V battery and a variable resistor and a couple of bits of wire on inputs 26,10, 11 until you can control the speed and direction to your
satisfaction....which will inform you as to how to wire the analogue inputs into your machine.
