Re: [CAD_CAM_EDM_DRO] Ways to convert step/direction signals to +/-10V analog

Hello group:

I am looking for a relatively inexpensive way to convert step/direction
signals from a PC parallel port to the +/- 10Vdc analog needed to control a
servor motor amplifier. I know that Gecko drives has a servo driver that
will do this and I have a couple ordered. The scenario I have is this: The
machines already have the servo amplifiers and motors on them and the motors
are much larger than the maximum allowed by the Gecko drives. There is a PC
system with a G-code interpreter on it that outputs step/direction signals
via the printer port, I need to use this to drive the servos.

Any help will be appreciated. I hate to purchase all new amplifiers that
will accept the step/direction signals if there is another, less expensive
way to do this.
