A motor driver SF/error disables driver (enable pin):

Start current:

Blocked mower blade (500 ms detection time, 5s wait time):
http://wiki.ardumower.de/images/1/18/Mower4_blocked_500ms_detect_5s_wait.png

In the Ardumower current code (detection time and very short wait time), the max. allowed power is 45 Watt (parallel dual driver) for no driver error to appear.

=> This power level could be set higher if the wait time is extended to 5 seconds.
