But, this one pulse each way thing is needed to clear the shutdown latch in the IR FET driver chip. The bootstrap supplies are kept charged any time the PWM signal is at "off", so that's every PWM cycle. I know Anders Wallin in Finland is using my servo amps with the Mesa controller, but I can't find a copy of his hal files to see if he did anything special to solve this problem.
