Mach4 General Discussion / AC Servo Load/Torque VU Meter?

« on: January 14, 2018, 07:28:35 AM »

Hi all im trying to make a 10 segment LED VU meter that will output the min and max torque from this servo motor, this will be a spindle load meter for my CNC Lathe, i have searched around but cannot seem to find a noob friendly tutorial about interfacing arduino or some other chip with an AC servo drive, the drive has Quadrature encoder Signals A B and Z out from the encoder of the motor it also has an analog speed and torque output, is there anyway i can make this output as a bar display, i want this to run on an arduino nano v3.0 if there is enough pins if not then it can be a larger one or some other chip, i was maybe thinking some kind of LM series driver for the display which i have uploaded a pic of the ones im using also added schematics of servo drive outputs, any help would be very much appreciated as i haven't a clue where to start with coding im good with circuits though, Cheers.
