Servo direction
« on: November 28, 2012, 11:09:21 AM »
Hello,

I have DSPMC V2. How i can give direction to inverter that have two digital inputs, one for each direction? I use Mach3. I know that Mach3 use pulse for step/dir but i have inverter with 2 digital inputs for direction and one analog 0-10V to control the speed of servomotor.

Thank you

What is the make and model of the drive/inverter that you are trying to run.
If it is a standard VFD, you use the analog output from the DSPMC to control the speed. You then assign 2 outputs from the DSPMC to give forward and reverse.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

I use ActiveCube inverter from Bonfiglioli (not step/dir controlled).

DSPMC need encoder for feedback if i use analog output and I don't have. I have closed loop servo - inverter with resolver.

I will try without encoder feedback.
