As a mechanical guy I usually just plow ahead and let the programmers figure that out

But on a more serious note at stall in low gear these motors will each draw 27-ish amps, so though that is enough to throw the breaker, I don't plan on stalling them, I plan on pushing people out of the way or breaking traction. In previous years we ran similarly geared 6CIM drives without issue unless we stalled in high gear. And I feel that the extra pushing power is always nice to have, motors can always be removed later.
