Does an F1 occur when decelerating?

If yes,

Then we suggest first observing whether the trip occurs when decelerating between speeds, decelerating to a stop, or decelerating during a reverse plug condition. The three deceleration parameters A4, A5, and A6 govern these three rates (respectively) and increasing the appropriate parameters may alleviate the problem. One could also set A5 and A6 to their maximum value and just increase A4 gradually to obtain a setting that will work. If increasing the time is unacceptable or does not work, try changing the voltage boost A8.
