Hello, I am using quadrature (rotary) encoders for motion control via external interupts for a master/slave(DC motor) setup. When I implement a large error (ie quickly moving my master encoder - or - step response). The PWM signal go crazy and unstable. The error between the master and slave encode…

What values of 'err' are you getting?
