Takeoff blocked: ESC RPM out of range

ArduCopter Copter 4.5
1

Hi
I tried a take of to do an initial hover test on a new build and have this message
‘Takeoff blocked: ESC RPM out of range’.
I have unsuccessfully checked my settings but unfortunately I need to help to fix this.

I am using the following.
Matek H743-SLIM V3
T-Motor F55A Pro II 55A 3-6s AM32 4-in-1

Below are my BLHeli ESC settings and I attach a log.

If anyone can help with this it would be appreciated!!

There is a takeoff mim rpm parameter in ArduCopter. It checks that the esc rpm telemetry is above it’s value. If not it refuses takeoff.

Correct it and it will work.

You have TKOFF_RPM_MIN,1400
Set it to 400
