I am using a SEW Frequency driver to control an AC Geared Motor.There is a incremental encoder on the High Speed Counter 1.I would like an example where an output changes from 1 to 0, when the hardware interrupt picks up that CV = RV.For example if you want to stop the motor at 1000mm, set RV = 1000.I have achieved this by slowing down the motor before the RV value, and not using interrupts, but this slows down the process.
CAN ANYONE HELP WITH THE EXAMPLE............
