I have already got a fail safe in that if the cct goes into over current for 1.6secs continuous (everything goes short and over current has no effect) then the main contactor is dropped out.

It sounds like you're writing your own software... is that right? If so, is your control scheme 'motor current' based? As in, the throttle is interpreted as a commanded output current and control loop uses the current sensor feedback to adjust the PWM duty cycle to match this commanded current?
