Hi,
I have started working on Pic based servo motor driver to interface with MACH 2/3 software the PIC will take input from Mach as step and direction and compare it with encoder pulses. It will generate pwm output to drive bridge for servo motor .I want to keep it simple as the motor tunning is done through Mach software. Pic will be 18F452 or 458.

can anyone help me for how make interface circuit between mach3 and dc servo motor with 3-axes mill machine?
Well its not polite to hijack a thread, and maybe the question was not properly formulated.Quote:

Now back to the PIC servo drive thread.

thanks for intersted and replying me
i know bob , i read this pdf but
first :i can't find it in my country
second: i have to do this circuit , it's my graduated project and my doctor 'll refuse this Suggestion
Motor tuning can't be done in Mach and have a system that responds quickly without oscillating.
For more information take a look at the Elm controller thread in the opensource forum.
Are you an EE or an ME?

thanks for help
i'm a mechatronics engineering
My Viper servo drive is a Pic based servo drive, so is the Rutex.
It took be about 8 months to get it perfected.

Allegro Micro has some good app notes and data sheets for stepper and DC motor drives.
